Re: What's the best way to ground the chamber?

<t>Grounding to the pin on the wall isn't really safe. It would likely work, however the wire won't be of sufficient gauge to handle a short circuit failure. It would be a good backup connection for safety. You should always ground everything at a minimum of double redundant when working with voltag...

Re: What is in a Rotary Vane pump rebuild kit?

<t>I just replaced my inlet-chamber seal and the shaft seal a few days ago and it took my 135 micron pump down to 33 micron. This was on a 1400 welch. Not sure if these would help yours or not. I don't know if the shaft seal helps vacuum or just oil leak, but I know the inlet chamber gasket is criti...

Re: Mark3 grid cooling system upgrades.

Make sure you always run that pump exactly in its designed orientation. I had a similar one cooling my computer loop and I put it at an angle once and it burned out within about a week.

Re: Kitchenaid fusor first light

<t>I don't think you'll get x-rays off of even parallel NST's. They simply can't provide necesary voltage, they're not designed to. You can read more about why they don't work with a search. I had 2 12,000 volt transformers (larger iron-core tranformers rather than the inverter that yours appears to...

Re: Kitchenaid fusor first light

<t>A great example of a low-cost plasma generator. Nice job!<br/> <br/> Regarding the x-rays, do you have a high voltage probe to measure the actual voltage or are you just assuming it's 15kv based on the power supply's rating? It looks like a small neon sign inverter which won't work to get anywher...

Re: Fusion Attempt Problems

I don't have control over the pressure of the electrolysis though (the very minute if even detectable "pressure"). How would I control the flow of fuel? I imagine you do it with the tanks regulator which I don't have

Re: Fusion Attempt Problems

Wish I had the money to do that. Also I'm not sure 1 sccm would be enough at the moment since my chamber has a 5 micron/sec leak so I'm basically running it with diffusion wide open. I need to work on that leak. Would teflon taped piping do that or is that sufficient for high vacuum?

Re: Fusion Attempt Problems

<t>I talked to Carl and he suggested starting the discharge at a higher pressure and then push it down very slowly and the voltage will go way up right before the discharge disappears. Perhaps doing this even without a ballast resistor.<br/> <br/> I tried this on the horrible needle valve I have (wh...
