Re: Fusor V construction - the process long running

At some point I will institute a new fusor V construction effort based on a spherical system. This fusor effort is now terminated the kludged fusor III in 2000 did far better at 150kn/s. I'll go with "easy", working the laws of physics to my total advantage. Smooth, even field distribution over a ne...

Re: Jim Kovalchick -My attempt at smaller fusor

Same here, the readings are dropping here as well. I never got even close to 100kn/s. Flash arcing will advance any neutron counting by >2k counts instantly, ruining the count run. Several arcs have been EMI powerful to the point that they have shut down the turbo supply (safety feature). (controlle...

Luke, I hope you get all of this straightened out. a PHA and MCA is a great thing to have working. It opens up a whole new world of nuclear capabilities.

Re: Coronavirus pandemic

That box was sent for 32 cents in 1961. I can remember the horror people felt when the postage leaped up 33% from 3 cents to 4 cents in late 1958 when I was 13. Today, a simple post card costs more to mail than the entire package above. We lived in the city, of course, and everyday, for 3 cents, the...

Re: Liquid cooled Demo Fusor cage

Funding is always an issue with the younger folks. Keep at it to the level you can with the demo and good luck.

Re: Fusor V construction - the process long running

The second drawing ( circles) is not related to the ion gun at all.. it is a totally separate idea for field emission ionization at the two conflat end plates to create local ionization in that desired region. The first drawing is the gun by itself. Yes, a magnet (premanent or coil) could be slipped...

Re: Coronavirus pandemic

Fabulous ionizing bandanna! Loved it! Funny in a time of lack of humor. A "positive" delight.

Re: Simple Cold Trap for PEM Cell Deuterium

This reminds me of the fabulous diffusion cloud chamber built in the Scientific American in the late 50's found in the "Amateur Scientist" section, always in the back of the magazine. It was constructed of copper and brass, the very large bottom tank was filled with the alcohol and dry ice mix. I bu...

Re: Coronavirus pandemic

Hey, With folks trapped at home in many instances, one might have expected a real flurry of Fusor activity. I would hope most who are not fusing are repairing stuff around home, reading the FAQs - (newbies), mowing lawns and doing other stuff. I just hope most aren't cowering in a corner, totally fr...
