Jim Kovalchick -My attempt at smaller fusor

Post by Jim Kovalchick » Fri Nov 29, 2019 8:46 pm

Holiday's for me mean leaving my apartment in Atlanta and getting back to my permanent home with my wife in South Carolina. That's also where my lab is. So, after a long absence I'm back at it.

I've been inspired by all the success with small fusors, so I'm going to give it a try too. Back when my son Mike was just in middle school (he's a PhD candidate now), he and I scrounged ebay for parts for his triboelectric xray generator. We found a working turbo and controller with a lot of misc vacuum parts sold as a lot. The turbo still sees use, but I wasn't sure we would ever use a CF 6 way cross in the pile. So here it is 2019 and the cross is looking pretty good.

I haven't made a grid yet, but I like the single electron axis pipe grids I'm seeing on the forum. The feedthrough is good to at least 30 kV because that's what Mike ran it too. He wrapped the post with several layers of Kapton, and I'm pretty sure it will do 40 that way.

I hope to get it under vacuum by the end of the weekend with Hope's for Christmas neutrons when I'm home next.

Cheers,

Jim K

Richard,
Well, ink-a dink-a doo.

I love neutrons and when I see Jon R pounding silver to 5000 cpm I want to be all about that even if it means copying.

As you can see from my recent post in construction, I am on my way there slowly with my 6 way cross.

I pulled first vacuum on the chamber this morning. A roughing pump that hasn't run since last winter brought vacuum down into uncalibrated single millitorr in less than 15 minutes. Small chambers are fun. I will eventually put it on a helium leak detector but will wait for all the rest of the connections and valves before I do it.
