1 00:00:03,300 --> 00:00:09,230 [Music] 2 00:00:14,539 --> 00:00:12,110 I work for a little company in Boulder 3 00:00:16,910 --> 00:00:14,549 called coalescence we're a privately 4 00:00:19,429 --> 00:00:16,920 funded group we've been doing ColdFusion 5 00:00:21,830 --> 00:00:19,439 work for the last seven years and we 6 00:00:24,350 --> 00:00:21,840 focus our work exclusively on 7 00:00:27,230 --> 00:00:24,360 experimental replication of work that 8 00:00:28,820 --> 00:00:27,240 has been published elsewhere as I get 9 00:00:32,720 --> 00:00:28,830 into this I'll try to deconstruct this 10 00:00:34,700 --> 00:00:32,730 title a little bit charge particles are 11 00:00:36,200 --> 00:00:34,710 things like alpha particles and there 12 00:00:37,970 --> 00:00:36,210 are evidence of cold fusion that's why 13 00:00:40,520 --> 00:00:37,980 it's interesting to look for it and I'll 14 00:00:43,280 --> 00:00:40,530 talk some about Co deposition which is a 15 00:00:46,700 --> 00:00:43,290 technique to initiate a cold fusion 16 00:00:51,259 --> 00:00:46,710 reaction let me start with a little bit 17 00:00:54,039 --> 00:00:51,269 of history before I got involved this 18 00:00:57,590 --> 00:00:54,049 Time magazine cover was kind of the 19 00:00:59,450 --> 00:00:57,600 beginning and end of my understanding of 20 00:01:00,770 --> 00:00:59,460 the field this was about the point where 21 00:01:02,660 --> 00:01:00,780 it was sort of made a big deal and then 22 00:01:06,020 --> 00:01:02,670 it kind of went away people thought it 23 00:01:07,250 --> 00:01:06,030 was sort of a hoax it turns out there's 24 00:01:09,590 --> 00:01:07,260 a number of people a couple hundred 25 00:01:15,399 --> 00:01:09,600 worldwide that have been working on it 26 00:01:20,539 --> 00:01:17,330 produced more heat than could be 27 00:01:23,260 --> 00:01:20,549 explained by known chemistry using a 28 00:01:26,389 --> 00:01:23,270 palladium deuterium electrolytic cell 29 00:01:27,980 --> 00:01:26,399 one of the questions the critics asked 30 00:01:29,870 --> 00:01:27,990 was well if this is really a nuclear 31 00:01:32,389 --> 00:01:29,880 reaction there should be some nuclear 32 00:01:35,480 --> 00:01:32,399 byproducts referred to by the cold 33 00:01:37,999 --> 00:01:35,490 fusion people this nuclear ash so what 34 00:01:40,789 --> 00:01:38,009 I'm going to talk about here is the look 35 00:01:42,349 --> 00:01:40,799 looking for that nuclear ash which in 36 00:01:44,690 --> 00:01:42,359 this particular case is charged 37 00:01:46,130 --> 00:01:44,700 particles a charged particle being 38 00:01:48,429 --> 00:01:46,140 something like an alpha particle helium 39 00:01:52,330 --> 00:01:48,439 nucleus or a proton or an energetic 40 00:01:58,459 --> 00:01:56,510 not long after well when in 1989 when 41 00:01:59,899 --> 00:01:58,469 the fields started everybody tried 42 00:02:04,660 --> 00:01:59,909 everything to see if they could recreate 43 00:02:07,910 --> 00:02:04,670 this a group led by Stan Spock 44 00:02:10,070 --> 00:02:07,920 who worked for a naval group out in San 45 00:02:13,070 --> 00:02:10,080 Diego described a technique called Co 46 00:02:15,590 --> 00:02:13,080 deposition in the original pons 47 00:02:17,780 --> 00:02:15,600 Fleischmann Cell the way that work is 48 00:02:20,480 --> 00:02:17,790 you had a Palladium cathode in heavy 49 00:02:22,559 --> 00:02:20,490 water and when you electrolyze water you 50 00:02:24,569 --> 00:02:22,569 pull hydrogen or 51 00:02:27,599 --> 00:02:24,579 this case deuterium to the cathode and 52 00:02:29,789 --> 00:02:27,609 oxygen forms at the anode and when you 53 00:02:31,440 --> 00:02:29,799 do that palladium is this magic material 54 00:02:34,860 --> 00:02:31,450 which absorbs lots of hydrogen or 55 00:02:37,140 --> 00:02:34,870 deuterium and when you get about 1/2 56 00:02:39,270 --> 00:02:37,150 Tyrion atom for every palladium atom in 57 00:02:42,000 --> 00:02:39,280 the lattice you get this reaction it 58 00:02:43,679 --> 00:02:42,010 takes a long time for that to occur so 59 00:02:46,410 --> 00:02:43,689 the breakthrough that Stan Spock 60 00:02:49,860 --> 00:02:46,420 described was a technique where you 61 00:02:52,619 --> 00:02:49,870 plate palladium out at the same time you 62 00:02:55,199 --> 00:02:52,629 electrolyze it and so you build this 1 63 00:02:59,339 --> 00:02:55,209 to 1 ratio right away the reaction 64 00:03:01,920 --> 00:02:59,349 starts more quickly in 2007 from the 65 00:03:04,140 --> 00:03:01,930 same group ammos your boss described a 66 00:03:05,970 --> 00:03:04,150 technique to find charged particles 67 00:03:08,759 --> 00:03:05,980 using a solid-state detector called CR 68 00:03:12,479 --> 00:03:08,769 39 which I'll talk more about as we get 69 00:03:14,369 --> 00:03:12,489 into this so what I want to talk about 70 00:03:17,069 --> 00:03:14,379 is kind of the search that we did in our 71 00:03:20,879 --> 00:03:17,079 laboratory to reproduce the work that 72 00:03:23,789 --> 00:03:20,889 was described by this naval group we 73 00:03:24,449 --> 00:03:23,799 thought this was important work for a 74 00:03:27,599 --> 00:03:24,459 couple reasons 75 00:03:29,069 --> 00:03:27,609 a number of people described seeing 76 00:03:32,610 --> 00:03:29,079 similar things so it would seem to be 77 00:03:33,809 --> 00:03:32,620 pretty reproducible charged particles 78 00:03:35,309 --> 00:03:33,819 were real interesting because they don't 79 00:03:37,349 --> 00:03:35,319 happen by accident they have to happen 80 00:03:39,599 --> 00:03:37,359 as a result of a nuclear reaction so we 81 00:03:40,649 --> 00:03:39,609 thought that was interesting and what 82 00:03:43,349 --> 00:03:40,659 I'm going to do it and go through this 83 00:03:46,559 --> 00:03:43,359 talk is kind of chronologically what we 84 00:03:48,089 --> 00:03:46,569 did in our search and what we found we 85 00:03:49,800 --> 00:03:48,099 went into this trying to answer the 86 00:03:51,659 --> 00:03:49,810 question is okay these charged particles 87 00:03:53,309 --> 00:03:51,669 are there what's the nature of them when 88 00:03:56,670 --> 00:03:53,319 do they occur what are their energies 89 00:03:58,559 --> 00:03:56,680 what can we learn about them all right 90 00:04:02,009 --> 00:03:58,569 let's talk a little bit about Co 91 00:04:05,339 --> 00:04:02,019 deposition I've got a little cartoon 92 00:04:07,610 --> 00:04:05,349 over there so you take a little cell you 93 00:04:10,050 --> 00:04:07,620 fill it full of electrolyte in this case 94 00:04:11,369 --> 00:04:10,060 you need some sort of assault in the 95 00:04:13,499 --> 00:04:11,379 electrolyte in order to make it conduct 96 00:04:16,050 --> 00:04:13,509 electricity in this case it's lithium 97 00:04:18,060 --> 00:04:16,060 chloride and then there's also a small 98 00:04:19,529 --> 00:04:18,070 amount of palladium chloride so when you 99 00:04:21,719 --> 00:04:19,539 pass a current through the cell you do 100 00:04:24,439 --> 00:04:21,729 two things you plate palladium out on 101 00:04:27,120 --> 00:04:24,449 the cathode and you also evolve 102 00:04:29,850 --> 00:04:27,130 deuterium from the cathode and oxygen 103 00:04:32,430 --> 00:04:29,860 from the anode this protocol is 104 00:04:33,659 --> 00:04:32,440 relatively slow it runs for a couple 105 00:04:34,769 --> 00:04:33,669 weeks and then you turn the current up 106 00:04:35,719 --> 00:04:34,779 and that's when interesting things 107 00:04:39,499 --> 00:04:35,729 happen 108 00:04:41,269 --> 00:04:39,509 experiment takes about three weeks we 109 00:04:42,769 --> 00:04:41,279 show here and lots of other people in 110 00:04:45,769 --> 00:04:42,779 the literature show these really 111 00:04:47,209 --> 00:04:45,779 interesting cauliflower like palladium 112 00:04:49,670 --> 00:04:47,219 deposits they have a lot of surface area 113 00:04:53,089 --> 00:04:49,680 and that's where the reaction is thought 114 00:04:56,059 --> 00:04:53,099 to occur so in the first phase of our 115 00:04:58,579 --> 00:04:56,069 study we said gee these charged 116 00:05:01,219 --> 00:04:58,589 particles exist what can we do to get 117 00:05:03,469 --> 00:05:01,229 more information about them so we used a 118 00:05:05,510 --> 00:05:03,479 scintillation detector and a simulation 119 00:05:07,399 --> 00:05:05,520 detector is a crystal or in some case an 120 00:05:08,809 --> 00:05:07,409 organic material that when you hit it 121 00:05:11,209 --> 00:05:08,819 with an energetic charged particle it 122 00:05:14,869 --> 00:05:11,219 makes light and then you can collect the 123 00:05:16,249 --> 00:05:14,879 light and figure out characteristics 124 00:05:20,119 --> 00:05:16,259 about when the particle arrived and how 125 00:05:21,829 --> 00:05:20,129 much energy it had radiation is a 126 00:05:24,290 --> 00:05:21,839 discrete events or every time you get a 127 00:05:26,540 --> 00:05:24,300 decay you get a flash of light and you 128 00:05:28,189 --> 00:05:26,550 typically put a counter behind it so we 129 00:05:30,350 --> 00:05:28,199 refer to counts as being a measure of 130 00:05:33,799 --> 00:05:30,360 the amount of radiation that was 131 00:05:35,719 --> 00:05:33,809 measured this is kind of a cartoon of 132 00:05:38,469 --> 00:05:35,729 what the first experiment looked like 133 00:05:41,659 --> 00:05:38,479 we've got this little electrolytic cell 134 00:05:43,820 --> 00:05:41,669 we make the cathode by putting a thin 135 00:05:46,129 --> 00:05:43,830 film of metal onto the scintillation 136 00:05:48,409 --> 00:05:46,139 crystal and then as you run the 137 00:05:50,239 --> 00:05:48,419 experiment you plate the plate palladium 138 00:05:52,760 --> 00:05:50,249 out which is those little irregular 139 00:05:54,199 --> 00:05:52,770 shaped blobs and on the side of the 140 00:05:56,149 --> 00:05:54,209 Palladium that faces assimilation 141 00:05:57,889 --> 00:05:56,159 crystal for reaction occurs you get a 142 00:05:59,839 --> 00:05:57,899 charged particle it doesn't have very 143 00:06:01,760 --> 00:05:59,849 far to go it goes into the scintillation 144 00:06:04,549 --> 00:06:01,770 crystal it makes light and it gets 145 00:06:07,369 --> 00:06:04,559 detected so in real life it looked like 146 00:06:12,320 --> 00:06:07,379 this these cells are about three inches 147 00:06:15,379 --> 00:06:12,330 tall this is the cathode right here it's 148 00:06:18,439 --> 00:06:15,389 the scintillation crystal with a metal 149 00:06:20,420 --> 00:06:18,449 film on it the vertical wires over here 150 00:06:22,909 --> 00:06:20,430 were the anode it was filled with this 151 00:06:24,290 --> 00:06:22,919 brown cocktail which was lithium 152 00:06:27,409 --> 00:06:24,300 chloride and palladium chloride in heavy 153 00:06:29,480 --> 00:06:27,419 water and then the backside of the 154 00:06:31,279 --> 00:06:29,490 scintillation crystal went up against a 155 00:06:33,290 --> 00:06:31,289 photomultiplier tube which is a light 156 00:06:35,719 --> 00:06:33,300 detection device and that whole device 157 00:06:37,540 --> 00:06:35,729 is sealed up in a dark chamber and the 158 00:06:44,449 --> 00:06:37,550 experiment runs for about three weeks 159 00:06:46,639 --> 00:06:44,459 what happened nothing that was bad we 160 00:06:48,559 --> 00:06:46,649 didn't see any increase in counts so we 161 00:06:49,939 --> 00:06:48,569 didn't see any charge particles above 162 00:06:53,419 --> 00:06:49,949 background 163 00:06:57,199 --> 00:06:53,429 of wanted it to we were seeing about 200 164 00:06:59,239 --> 00:06:57,209 counts a day of background so it meant 165 00:07:01,369 --> 00:06:59,249 that if we got a lot of energy all at 166 00:07:03,949 --> 00:07:01,379 once we certainly would see it if we got 167 00:07:05,569 --> 00:07:03,959 particles counts it showed up uniformly 168 00:07:08,029 --> 00:07:05,579 over the two-week period we probably 169 00:07:09,499 --> 00:07:08,039 wouldn't see it whenever you're doing a 170 00:07:12,139 --> 00:07:09,509 replication you get a negative result 171 00:07:13,459 --> 00:07:12,149 the first question you ask is okay did 172 00:07:16,279 --> 00:07:13,469 we run the right experiment did we 173 00:07:18,349 --> 00:07:16,289 create the right conditions or did or 174 00:07:19,279 --> 00:07:18,359 can we explain the negative result by 175 00:07:22,489 --> 00:07:19,289 the fact we didn't run the right 176 00:07:25,009 --> 00:07:22,499 experiment which led us to the second 177 00:07:27,139 --> 00:07:25,019 set of our experiment which was to try 178 00:07:30,289 --> 00:07:27,149 to understand you know why didn't the 179 00:07:32,479 --> 00:07:30,299 first one work in order to do that we 180 00:07:34,489 --> 00:07:32,489 decided to run two cells at the same 181 00:07:36,559 --> 00:07:34,499 time one of them like the one I just 182 00:07:39,949 --> 00:07:36,569 described and the sewol we were going to 183 00:07:42,469 --> 00:07:39,959 use the Sierra 39 whoops detector that 184 00:07:44,659 --> 00:07:42,479 the the Navy group had used so let me 185 00:07:47,419 --> 00:07:44,669 tell you a little bit about CR 39 and 186 00:07:49,999 --> 00:07:47,429 how it works on the right hand side is a 187 00:07:51,589 --> 00:07:50,009 little piece of CR 39 it's plastic it's 188 00:07:53,629 --> 00:07:51,599 the same material your eyeglasses are 189 00:07:56,149 --> 00:07:53,639 made out of in this case it's made in 190 00:07:58,969 --> 00:07:56,159 really thin sheets and it's extremely 191 00:08:01,129 --> 00:07:58,979 pure doesn't have any holes in it it has 192 00:08:02,809 --> 00:08:01,139 the characteristic if you hit it with an 193 00:08:06,199 --> 00:08:02,819 energetic charged particle the charged 194 00:08:08,629 --> 00:08:06,209 particle damages the plastic and then 195 00:08:10,909 --> 00:08:08,639 you after you've run your experiment you 196 00:08:13,219 --> 00:08:10,919 develop it if you will by edging the 197 00:08:14,989 --> 00:08:13,229 material in a hot life solution and then 198 00:08:17,659 --> 00:08:14,999 you read it by looking at it with a 199 00:08:19,879 --> 00:08:17,669 microscope see you have 39 is an 200 00:08:21,919 --> 00:08:19,889 integrating detector what that means is 201 00:08:23,629 --> 00:08:21,929 that any particle that hits it from the 202 00:08:26,209 --> 00:08:23,639 time it was born until you develop it 203 00:08:28,459 --> 00:08:26,219 get recorded so you could detect very 204 00:08:30,169 --> 00:08:28,469 low levels of activity the bad news is 205 00:08:35,719 --> 00:08:30,179 you have no idea when that activity 206 00:08:37,429 --> 00:08:35,729 occurred in order to count it you can do 207 00:08:39,589 --> 00:08:37,439 it by hand and you do that for about two 208 00:08:42,290 --> 00:08:39,599 days and you go nuts we ended up 209 00:08:44,329 --> 00:08:42,300 building a an automatic scanner which 210 00:08:46,939 --> 00:08:44,339 was a microscope on a three axis stage 211 00:08:49,340 --> 00:08:46,949 it's just sort of ran across the piece 212 00:08:51,350 --> 00:08:49,350 of CR 39 taking two to four thousand 213 00:08:55,040 --> 00:08:51,360 images and then we crunch those images 214 00:08:58,639 --> 00:08:55,050 with some computer programs and it 215 00:09:00,290 --> 00:08:58,649 results in little montages of tracks so 216 00:09:02,629 --> 00:09:00,300 this is what our radiation track looks 217 00:09:03,240 --> 00:09:02,639 like those little squares represent 218 00:09:05,340 --> 00:09:03,250 about 50 219 00:09:10,170 --> 00:09:05,350 microns of distance on a piece of CR 39 220 00:09:15,350 --> 00:09:10,180 plastic so this is the cartoon of what 221 00:09:18,050 --> 00:09:15,360 the Serie 39 experiment looks like 222 00:09:20,610 --> 00:09:18,060 similar to the other experiment we had a 223 00:09:23,100 --> 00:09:20,620 wire which is a cathode 224 00:09:24,830 --> 00:09:23,110 a piece of the CR 39 plastic which is 225 00:09:27,750 --> 00:09:24,840 inside the cell with the electrolyte 226 00:09:29,850 --> 00:09:27,760 again the Palladium forms on the wire if 227 00:09:32,250 --> 00:09:29,860 the reaction occurs on the CR 39 side 228 00:09:35,280 --> 00:09:32,260 charge particles hit to see our 39 and 229 00:09:40,350 --> 00:09:35,290 make tracks in real life it looked like 230 00:09:41,730 --> 00:09:40,360 this the top picture is the cell with a 231 00:09:44,970 --> 00:09:41,740 scintillation crystal which is that 232 00:09:46,500 --> 00:09:44,980 round disc the cathode wires ran 233 00:09:47,940 --> 00:09:46,510 horizontally and then behind it you 234 00:09:50,520 --> 00:09:47,950 can't really see the anode wires ran 235 00:09:53,130 --> 00:09:50,530 vertically and the lower picture is the 236 00:09:57,510 --> 00:09:53,140 same thing with the CR 39 so we ran 237 00:09:59,100 --> 00:09:57,520 those two cells at the same time this is 238 00:10:03,350 --> 00:09:59,110 interesting we saw some good stuff here 239 00:10:06,930 --> 00:10:03,360 and curious we didn't see anything on 240 00:10:11,910 --> 00:10:06,940 the scintillation counter but on the CR 241 00:10:14,340 --> 00:10:11,920 39 we saw all sorts of good stuff this 242 00:10:15,480 --> 00:10:14,350 picture here is what the physical part 243 00:10:17,280 --> 00:10:15,490 looked like when we brought it out so 244 00:10:19,170 --> 00:10:17,290 there was physical evidence you could 245 00:10:23,700 --> 00:10:19,180 see where the lines were and if I blew 246 00:10:25,829 --> 00:10:23,710 those up with a microscope I see all 247 00:10:28,829 --> 00:10:25,839 sorts of tracks here and this 248 00:10:31,380 --> 00:10:28,839 representation on the right side is the 249 00:10:33,180 --> 00:10:31,390 spatial track density so in the area 250 00:10:36,510 --> 00:10:33,190 where the cathode is you've got the 251 00:10:41,310 --> 00:10:36,520 elevated counts what's interesting here 252 00:10:43,590 --> 00:10:41,320 is the number of counts was well larger 253 00:10:45,360 --> 00:10:43,600 than our background so if those counts 254 00:10:46,680 --> 00:10:45,370 represented charged particles we should 255 00:10:50,370 --> 00:10:46,690 have seen something on our scintillation 256 00:10:53,400 --> 00:10:50,380 counter which begged the question why 257 00:10:55,950 --> 00:10:53,410 not which brought us into the third 258 00:10:59,220 --> 00:10:55,960 phase of the experiment which was okay 259 00:11:00,750 --> 00:10:59,230 we see counts on the CR 39 how come we 260 00:11:03,150 --> 00:11:00,760 didn't see counts on the scintillation 261 00:11:06,570 --> 00:11:03,160 counter one of the criticisms that was 262 00:11:09,090 --> 00:11:06,580 mounted in the the field of this 263 00:11:10,860 --> 00:11:09,100 experiment was CA 39 is traditionally 264 00:11:13,140 --> 00:11:10,870 used in high-energy physics experiments 265 00:11:16,380 --> 00:11:13,150 in a vacuum chamber which is pristine 266 00:11:18,420 --> 00:11:16,390 and clean there were some 267 00:11:20,610 --> 00:11:18,430 criticisms that putting CR 39 into the 268 00:11:23,280 --> 00:11:20,620 electrolyte might allow the electrolyte 269 00:11:26,790 --> 00:11:23,290 to damage the CR 39 and make fake tracks 270 00:11:28,110 --> 00:11:26,800 if you will so the Navy Group came up 271 00:11:31,560 --> 00:11:28,120 with an experiment where they protected 272 00:11:34,290 --> 00:11:31,570 the Sierra 39 with mylar and we set out 273 00:11:36,800 --> 00:11:34,300 to reproduce that experiment exactly 274 00:11:39,750 --> 00:11:36,810 I might make a note that one of the 275 00:11:41,610 --> 00:11:39,760 Leonard researchers lectures is about 276 00:11:43,160 --> 00:11:41,620 constantly and that is if you're going 277 00:11:45,300 --> 00:11:43,170 to reproduce somebody's experiment 278 00:11:46,770 --> 00:11:45,310 reproduce their experiment don't make it 279 00:11:49,440 --> 00:11:46,780 better so what we did here was exactly 280 00:11:51,720 --> 00:11:49,450 the opposite we made it better and then 281 00:11:53,270 --> 00:11:51,730 about a year later we finally got to 282 00:11:57,000 --> 00:11:53,280 doing what we should have done at first 283 00:12:00,020 --> 00:11:57,010 but this is what we did okay so this is 284 00:12:02,640 --> 00:12:00,030 a cartoon of the mylar protected sea r39 285 00:12:05,640 --> 00:12:02,650 we cut a hole in the cell this little 286 00:12:08,640 --> 00:12:05,650 plastic box and we covered that hole 287 00:12:10,590 --> 00:12:08,650 with a mylar window the mylar was very 288 00:12:13,020 --> 00:12:10,600 thin so that the charged particles could 289 00:12:14,790 --> 00:12:13,030 pass through it without any problem and 290 00:12:17,130 --> 00:12:14,800 then the Sierra 39 was on the outside of 291 00:12:19,680 --> 00:12:17,140 the window not in the in contact with 292 00:12:23,310 --> 00:12:19,690 the electrolyte so again if a reaction 293 00:12:25,140 --> 00:12:23,320 occurs on the mylar side of the little 294 00:12:28,230 --> 00:12:25,150 palladium deposit the charge particle is 295 00:12:29,760 --> 00:12:28,240 generated passes through the through the 296 00:12:33,270 --> 00:12:29,770 mylar window hits the Sierra 39 and 297 00:12:37,770 --> 00:12:33,280 makes a track in real life it looked 298 00:12:39,390 --> 00:12:37,780 like this the mylar window was 6 microns 299 00:12:41,610 --> 00:12:39,400 to put that in perspective a piece of 300 00:12:43,290 --> 00:12:41,620 paper is about 10 times that size it's 301 00:12:49,200 --> 00:12:43,300 about 50 to 100 microns so this is 302 00:12:51,210 --> 00:12:49,210 really thin the cathode wire is pressed 303 00:12:53,940 --> 00:12:51,220 up against the CR 39 and then up against 304 00:12:55,980 --> 00:12:53,950 the up against the mylar then the COR 39 305 00:12:58,320 --> 00:12:55,990 the charged particles pass through with 306 00:13:01,290 --> 00:12:58,330 very little attendant attenuation in 307 00:13:02,940 --> 00:13:01,300 addition to the CR 39 we also monitored 308 00:13:04,830 --> 00:13:02,950 some chemical characteristics of the 309 00:13:06,360 --> 00:13:04,840 cell we monitor this voltage and the pH 310 00:13:07,740 --> 00:13:06,370 and some things like that to get a 311 00:13:12,150 --> 00:13:07,750 better idea of what might be going on 312 00:13:13,350 --> 00:13:12,160 inside these cells what do we see well 313 00:13:16,950 --> 00:13:13,360 in all the cells that we ran with 314 00:13:20,420 --> 00:13:16,960 deuterium we saw significant increase in 315 00:13:23,490 --> 00:13:20,430 tracks in the area of the cathode and 316 00:13:25,170 --> 00:13:23,500 here you can see you know this is what 317 00:13:28,530 --> 00:13:25,180 the tracks look like in the microscope 318 00:13:29,920 --> 00:13:28,540 and they showed up here in the area of 319 00:13:35,120 --> 00:13:29,930 the cathode 320 00:13:38,210 --> 00:13:35,130 what did that mean we looked at the 321 00:13:40,550 --> 00:13:38,220 tracks and we observed as as others that 322 00:13:45,530 --> 00:13:40,560 observe before us that the tracks 323 00:13:48,260 --> 00:13:45,540 produced by the the electrolytic Co 324 00:13:52,160 --> 00:13:48,270 deposition process didn't look like 325 00:13:54,740 --> 00:13:52,170 tracks we got from calibration and the 326 00:13:58,730 --> 00:13:54,750 Lord said these tracks were produced by 327 00:14:01,190 --> 00:13:58,740 taking a known 5 MeV alpha emitter which 328 00:14:02,720 --> 00:14:01,200 was polonium-210 and exposing that to 329 00:14:04,280 --> 00:14:02,730 the CR 39 and then going through the 330 00:14:06,550 --> 00:14:04,290 development process and you get these 331 00:14:09,920 --> 00:14:06,560 really round or elliptical shaped 332 00:14:11,360 --> 00:14:09,930 distinct tracks the shape is a function 333 00:14:15,170 --> 00:14:11,370 of the angle that the particle hits the 334 00:14:16,640 --> 00:14:15,180 CR 39 with it hits dead-on there they're 335 00:14:19,040 --> 00:14:16,650 round otherwise are a little elliptical 336 00:14:22,160 --> 00:14:19,050 and up here we saw tracks that look very 337 00:14:25,250 --> 00:14:22,170 different which raised the question ok 338 00:14:29,030 --> 00:14:25,260 what what maybe made those the other 339 00:14:30,640 --> 00:14:29,040 thing we noted you know these cells run 340 00:14:33,680 --> 00:14:30,650 for three weeks and the cells 341 00:14:35,870 --> 00:14:33,690 particularly after electrolysis and a 342 00:14:40,190 --> 00:14:35,880 heavy water environment were clearly 343 00:14:42,730 --> 00:14:40,200 damaged the other thing we noted is in 344 00:14:46,700 --> 00:14:42,740 every case where we have elevated tracks 345 00:14:49,400 --> 00:14:46,710 the area where the tracks were elevated 346 00:14:51,770 --> 00:14:49,410 we saw something on the CR 39 we saw 347 00:14:53,660 --> 00:14:51,780 stuff like this you know the micrograph 348 00:14:55,700 --> 00:14:53,670 of a little blow-up look you know lots 349 00:15:00,380 --> 00:14:55,710 and lots of activity which correspond 350 00:15:03,110 --> 00:15:00,390 into regions that had high counts if you 351 00:15:04,790 --> 00:15:03,120 take CR 39 and put it in a vacuum 352 00:15:06,620 --> 00:15:04,800 chamber and expose it to a radioactive 353 00:15:08,150 --> 00:15:06,630 source you don't see anything to the 354 00:15:10,370 --> 00:15:08,160 naked eye you see it in the microscope 355 00:15:12,050 --> 00:15:10,380 but not to the naked eye so that made us 356 00:15:16,220 --> 00:15:12,060 a little suspicious that maybe something 357 00:15:18,440 --> 00:15:16,230 else was going on I'm not going to say 358 00:15:20,320 --> 00:15:18,450 much about this other than there was 359 00:15:23,240 --> 00:15:20,330 significant evidence from our 360 00:15:24,140 --> 00:15:23,250 measurement of pH and cell voltage and 361 00:15:26,180 --> 00:15:24,150 stuff like that there's a lot of 362 00:15:29,060 --> 00:15:26,190 chemistry going on inside the cell the 363 00:15:31,580 --> 00:15:29,070 pH goes from kind of acidic to real 364 00:15:33,170 --> 00:15:31,590 acidic up to very basic and there was 365 00:15:36,790 --> 00:15:33,180 also a period where we're making hypo 366 00:15:40,880 --> 00:15:36,800 chloride ions which is basically bleach 367 00:15:42,200 --> 00:15:40,890 so that made us ask is there any way 368 00:15:43,040 --> 00:15:42,210 that the chemistry in the cell is 369 00:15:47,510 --> 00:15:43,050 damaging 370 00:15:49,730 --> 00:15:47,520 the the CR 39 one of our colleagues at 371 00:15:50,990 --> 00:15:49,740 the Naval Research Lab suggested well 372 00:15:52,730 --> 00:15:51,000 why don't you put some aluminum foil on 373 00:15:54,770 --> 00:15:52,740 it aluminum is pretty easily attacked by 374 00:15:57,740 --> 00:15:54,780 chlorine we did that in two different 375 00:15:59,690 --> 00:15:57,750 ways we put some strips of aluminum on 376 00:16:02,450 --> 00:15:59,700 and we also after we had built one of 377 00:16:04,970 --> 00:16:02,460 these cells we had a phenol thin film of 378 00:16:07,730 --> 00:16:04,980 my aluminum put on the mylar sheikhan 379 00:16:09,320 --> 00:16:07,740 slips as you can see here it was pretty 380 00:16:11,780 --> 00:16:09,330 much destroyed and we had evidence of 381 00:16:14,090 --> 00:16:11,790 damage here the final experiment we did 382 00:16:16,910 --> 00:16:14,100 was we introduced a small air gap a half 383 00:16:20,480 --> 00:16:16,920 a millimeter air gap which is not enough 384 00:16:23,450 --> 00:16:20,490 to significantly lower the energy of 385 00:16:25,310 --> 00:16:23,460 charged particles and what we saw was in 386 00:16:27,710 --> 00:16:25,320 the case where we didn't have an air gap 387 00:16:29,450 --> 00:16:27,720 we had elevated counts in the cases 388 00:16:33,550 --> 00:16:29,460 where we did have our gaps the counts 389 00:16:37,300 --> 00:16:33,560 went away so in summary we never saw 390 00:16:41,570 --> 00:16:39,710 we saw tracks even in the mylar 391 00:16:44,540 --> 00:16:41,580 protective Sierra 39 cell as well so 392 00:16:47,000 --> 00:16:44,550 cells without the mylar the tracks look 393 00:16:48,620 --> 00:16:47,010 different from normal alpha tracks the 394 00:16:51,560 --> 00:16:48,630 track location correlated well with 395 00:16:55,220 --> 00:16:51,570 damages mylar didn't prevent damage to 396 00:16:59,200 --> 00:16:55,230 the foil and if we put an air gap in the 397 00:17:01,340 --> 00:16:59,210 tracks all went away so we concluded 398 00:17:06,050 --> 00:17:01,350 unfortunately not what we wanted to find 399 00:17:08,329 --> 00:17:06,060 when we set out we concluded that the 400 00:17:12,670 --> 00:17:08,339 likely cause of the CR 39 tracks was 401 00:17:15,410 --> 00:17:12,680 chemical damage not nuclear activity and 402 00:17:19,310 --> 00:17:15,420 in all the runs we did
