Re: Need to ground implosion screen?

Wilfried has got good advice. It's better to ground and err on the side of safety, unless of course you're intentionally floating something.

Re: Positive HV Fusor

<t>I've often wondered why not two grids, the outer one at HV+ and the inner either at ground or at -100V or so. The shell, of course, would still be grounded and neutral. If that configuration would work one could use the cheaper and more readily available HV+ supplies, and a cheap lab supply. The ...

Re: Achieved - Meiro demo fusor

My Spanish is very rusty, however when they introduce him, they say his name is Meiro, and when he's talking about the reactor (the grid to be specific but I'm not sure) he describes it as a "Meiro Grid".

Re: Vacuum pump

<t>You should really use the search tool in this forum, operating pressures (mean free path), vacuum pumps, and d2 density have discussed numerous times, and are in the FAQs. <br/> <br/> Typically working fusors operate at a few microns or so. Pressure is dependent on the amount of current a power s...

Re: Building physics instruments

<r>I actually picked up a copy of the book from the University library. It's probably the number one book to read/have if you're planning to build a fusor, especially if you have no relevant skills. Interestingly enough, this fantastic book is online free for all to read. <br/> <br/> <URL url="http:...

Re: Ready for HEAS 08

Unlike Steven I'll be only tens of miles away from Richmond. However school keeps me occupied elsewhere. Good luck with the new D2, and HEAS! Maybe next year....
Enjoy,
