Re: Fusor construction questions

I didn't want to have to a buy an 8" conflat gate valve as those run over $1000. Is fusion totally impossible without one? I do have the turbo throttled down to 20% power if that helps any.

Re: 2200 l/s turbos

I don't have the skill to make that controller so I'll probably just keep them around then.

Re: Fusor construction questions

Im somewhat confused. My shutdown procedure is: shutdown_diagram.png 1. Turn off turbo pump and wait for it to stop spinning 2. Close ball valve and then open turbo's bleed valve to put chamber back to atmosphere 3. Open KF16 connection to let air into the backing pump and immediately after turnoff ...

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...

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. Also I originally had 40" of kf16 tubing inbetween the pumps so I cut it down to 20". Neither of these made any difference...

Re: Fusor construction questions

Peter, thanks for the sieve idea. Right now I've got that third smaller chamber in the picture which is filled with drierite. Its good to hear the drier isnt necessary but I'll keep it just in case.

Re: Fusor construction questions
