Re: Archived - First Fusion for Bob Reite

hello, I m on the way to build a fusion reactor, and i will post very soon a complete description of my project. For the time being I m still designing the key components, beginning with the deutérium générator. In france, you cannot buy deuterium, so i need to générate it. I ve seen on an other pos...

Re: A new topology for building a low-cost DIY HV power supp

hello chris, after a long time of heavy workload, I m back to go on my projects and one of these is still to reproduce your epicyclotron experiment. I ve found a suitable "multipurpose" vacuum chamber, completed my vacuum system and now I ve to build my négative HV PSU for the outer electrodes. I ‘m...

Re: new automated vacuum system

hello philipp the diffstak 63/150 requires a minimum flow of 42 l/h for cooling water. I ve built the water cooling system from used automotive spare parts. It is not yet mounted in the rack, but i ve tested it in july. - a facet pump, normally used for fuel injection - pressure: 0,5 bars, flow: 150...

new automated vacuum system

Hello, I m on the way to complete my multipurpose automated vacuum system from the parts of an old project. My main goal is still to embody the work done by chris bradley on the "epicyclotron", well described in this forum. As i also plan to conduct further particles physics experiments, I realize t...

Re: Feedthrough arrangements on my epicyclotron prototype.

hello chris, thanks a lot for your answers, it helps me a lot to figure out the concept. I m on the way to finish the translation of the detailed description in the patent, and i have to take time to remind or sometimes learn all the theorical knowledge in physics which is necessary. I ve made a com...

Re: Feedthrough arrangements on my epicyclotron prototype.

Hello chris, I m back in the amateur physics world after more than a year, busy by others projects and workload. Among a lot of ambitious projects I m still on the way to try to reproduce your epicyclotron experiment in my small private lab. The first attempt one year ago was stopped by my poor vacu...

Re: Feedthrough arrangements on my epicyclotron prototype.

<t>hello chris, <br/> <br/> can you please explain the need of height feedthroughs for the epicyclotron project ( perhaps only for the bottom plate ?) ?<br/> <br/> I understand quite well the need for the four electrodes, but do you intend to test your concept of four independant wires for the centr...
