Re: Where to buy an x-ray power supply?

zhgreader,
That's an American measuring tape, so it's 11 inches, and closer to 30cm.

Re: plasma focus

<t>with the chamber and the cathode being grounded to the wall socket.<br/> <br/> I'm not quite sure what you mean by the cathode and chamber being grounded...The cathode should be at negative HV, and the chamber, if it's metal, should be grounded. There should be no resistance on the chamber / grou...

Re: curious if this is possible

<t>16Teslas is fairly strong field, as in there are about 1-2Teslas in an MRI...So to answer your question, yes the credit cards would probably be wiped clean and you'd have to worry about the magnet pulling everything ferrous in room towards it, including the hardware holding the room together. <br...

Re: What do you think?

I'd have to echo Steven, many ebay dealers offer just the pumps, and it takes a lot of resources to build a pump. If you have the CNC available you could look into making the vacuum chamber, and flanges.

Re: HV diode

They sure can. You're going to want to make sure that you have enough distance between the diodes so that there won't be any arcing. So for 5.6 kV put 6 or 7 diodes in series, and if you want submerge in oil.

Re: TC gauge sensitivity?

<t>TC gauges don't really go bad per say. They're simply two wires joined thermally, one is heated and the other one is used to measure resistance, so if the wires haven't broken I'd say that the gauge head probably works just fine. The controller is probably OK. You might need to adjust the zero po...

Re: A few noob questions

<t>I'll answer these briefly:<br/> 1. Yes, Dan Tibbets - screen name "Dan DT", has made a pressure cooker "demo" fusor. Under recent threads there's a lengthy post about his demo fusor and the effect of magnets on the plasma. <br/> <br/> 2. Very carefully. There are also a lot of threads devoted to ...
