Great points Jim! You tend to back up my activation presentation above. Net Zero thermal flux during the Gonzo mode making all normal activation statistics null and void. Any attempts at recreation of the claimed event are equivalent to a snipe hunt, in my mind. Like Farnsworth, Doug is gone. Legends and tales of amazing claims live long afterwards.

I seem to recall that what became activated were steel wrenches and lathe tool bits containing some small amount of cobalt. (Cobalt-steel)

So I wasn't there during Doug's , I will say "claimed" to appease everyone, run. I thank God I wasn't. I too only know what Doug told me. He said he was tweaking knobs etc, and suddenly heard a searing, white noise type of sound coming from the from the speakers. He had attached an audio amp and speakers to the output of the neutron tube so he could "hear" the relative neutron output from the He3 tube. He learned of this Idea from Richard. He said all of his equipment was "flooded" or maybe shutdown, can't remember precisely. During a normal run the audio sounded like heavy rain on a tin roof. He immediately couldn't figure out what was wrong. I can understand that as I have a radiac set I purchased from Richard that I run to listen to cosmics. I came home one day after a tec99 heart scan and heard a searing screaming sound. I immediately couldn't understand what was going on either, until I realized it was "Me" causing the screaming.
Doug was immediately bed ridden after the "accident" with vomiting and diarrhea for about two weeks. A curious scientist would speculate a cause and effect relationship between the events. Additionally, Doug never got a cold or anything during the time I knew him. I suspect his close relationship with microbes helped out his immune system as he wasn't really good at hygiene, so the i discounted the idea that he may have had the flu or something after the event. I always took my own food and drink to Doug's and would sometimes come home looking like a "coal miner" after crawling around some of the equipment or running wires underneath etc.
I had come upon a "stash" of Woods metal that melts at 158 degrees. We used it to "shield" a lot of stuff around the fusor because it was so easy to cast. After the event I had it analyzed at a scrap yard. It contained about 10 per cent cadmium. Doug looked up the neutron data on cadmium and realized it gives of a 9mv gamma from neutron capture. Doug thought and probably rightly so that the cadmium helped "cook" him. I think in a discussion with Richard, Richard had stated that he thought Doug had had excessive xray exposure. We immediately removed all the woods metal.
I was up at Doug's about two weeks after the "event" I scanned the room with my survey meter and found no excessively high background. Doug never lost his hair that I knew of.
I have no doubt that "something" happened with the fusor to make Doug sick. His close neighbor confirmed Doug was "really sick" for about two weeks. His neighbor is an EMT. I believe the fusor got into some sort of positive feedback mode and pumped out an incredible amount of neutrons and gamma rays, how many, no one knows.
Yes, there are no "pictures or it didn't happen" data to go with this, only Doug's account and what Doug told me. So I will leave it up to you to think what you think.

Bill,
I believe that something happened though I'm not sure the activation story makes sense.

I have seen ridiculous short transient neutron numbers on my fusor. With my current BF3 tube that usually reads 20 kcpm at 45 kV and 10 mA, I have seen the needle spike to the end of scale at 500 with a 1k multiplier on my ludlum 2200. I am not sure if it was real or noise because the transients last only a few seconds. They have been coincident with reaching a high shell temperature. So, one theory is that the shell released a bunch of D all at once. I saw Richard's fusor have similar neutron transients last October at HEAS.

Maybe that's what Doug saw.

Again, Bill gives us more good info on Doug and the event. Bill was about as close to Doug in a scientific sense as anyone around him as a regular in-person helper/assistant. I some times see Bill at hamfests and we chat a bit. He is often at the HEAS October events and has even showed up here on his own for a short visit.

Jim,
I’ve had the same brief spikes with a very similar neutron detection arrangement (Ludlum 2221 / CHM11 and CHM14 detector tubes). Luckily, I’ve experienced the condition several times while using a bubble detector. At no time did they reflect any increase in neutron production. I still contend the anomaly is either an electron runaway effect near the grid stalk causing electrical noise interference OR some type of high tension corona issue causing similar results. Fwiw, I’ve only noticed these brief occurrences while operating above 45kV. It was also more prevalent in the small cross fusor than the larger one I’m currently operating.

Bill, what do you mean by “positive feedback mode”?

Side note…
I know this whole thing is sensitive topic however, since Dougs fusor is being rebuilt with Gonzo Mode as the end goal, it’s important to highlight what he (Doug) had previously defined as “Gonzo Mode” in the old posts. That definition is the criteria that has to be met for successful replication.

With that being said, it does not undermine the astute technological advances Doug incorporated with his system. There have been quite a few highly respected folks observe his fusor churning out some phenomenal numbers. Numbers that, in my opinion, are not obtainable with the classic design. Undoubtedly we all can learn a lot from his advances.

By positive feedback I meant Doug's fusor was basically a triode set up as an oscillator. -bill

Mark,
I'm not using a Russian tube anymore, but the phenomenon could still be noise.

To Joe Gayo and others: The theoretical discussion of operating a fusor as an electronic oscillator and how "Gonzo Mode" might work is under another topic titled "Fusor as an oscillator, a serious discussion". I will continue to use this topic to post the reassembly progress and operational results obtained once put back together.
The more reactive the materials, the more spectacular the failures.
The testing isn't over until the prototype is destroyed.

Thanks Bob! I was getting ready to suggest that....Yo beat me to it. Definitely let this thread be about the re-assembly and testing of Doug's fusor with plenty of images as you get time to take photos of your progress. I am interested enough in what Doug claimed, and built his theories around, to feel it deserves the attention that we might give it in discussion and perhaps experiment. the serious discussion can be picked up at......
