Re: Fusor construction questions

Should I turn off my backing pump when its still connected to the pumped down chamber and then open it up to atmosphere once its off or do I open it up to atmosphere and then turn it off? I've been doing the latter but after a couple times the pump now hums for a couple of seconds after I turn it on...

2200 l/s turbos

A while back I acquired two Mitsubishi Sinchoon FT2200W turbos. Since the controllers and cables are no where to be found do yall have any ideas on what to do with them? If anyone knows anyone who might be interested in purchasing them or any way to turn these on without controllers and cables that ...

Re: Fusor construction questions

If e-4 torr acceptable for fusion? That's the lowest that I can get my chamber to. I originally was using used conflat gaskets so I swapped to new properly torqued down gaskets.

Re: Fusor construction questions

Fusor construction questions

I've finished the fusor but my deuterium setup isn't really working. I'm using the PEM cell design with the over and under pressure chambers. I open the needle valve to evacuate the air from the deuterium chamber and then I turn on the PEM cell to displace the oil with deuterium. However, instead of...

I'm applying to the plasma club with this.

Re: X-ray transformer issues

Okay thanks for pointing those out.

I just made a new grid and I'll machine some new supports from porcelain tile.

Also the XRT works great. I've been playing around with it at 30kv and getting some nice arcs.
