More 'plasma jar' experiments.

In this video, i used an A/C compressor as a backing pump (or forepump if you'd rather that) to try to get a lower ultimate vacuum. Also, i put a ring magnet on the - electrode which has a pretty neat effect.

I now need a vacuum gauge so that i can see what pressure it is, and see if the backing pump actually helps anything.

Nice plasma. I have done that to and I wonder if it could make X-ray radiation seems that with a magnetic field to accelerate the electrons it could be even more likely you should get some film I've heard that polaroid film well work . I Like your videos alot :)

@plumcrazzzy thanks for the kind words. X-rays are possible, but a much harder vacuum would be required, probably a micron or less. However, with a proper vacuum pump, making the tube would be easy other than sealing. Cold cathode mode works fine, especially if you use a high voltage high current pulse and run it as a pulse x-ray tube. I don't think magnetic fields would do too much for an xray tube though.

Nice work, what is the power source?

[triggerhappy77707]

@sirHOAX Other than ghetto? :-P It was a MOT with it's primary driven by an 80v transformer (for the sake of isolation and current limiting for safety), and 110kohms in series to limit the current to the jar.

@triggerhappy77707 looks like fun. know you can find 1-to-1 isolation transformers in high-pressure-sodium lights, if i'm not mistaken. they use them for limiting current the same.

[triggerhappy77707]

@sirHOAX Well technically they are ballasts, but they could be used the same. But why use that when i could just use an 80v transformer i already had? :-P. I could just use an inductor in series with the power supply MOT to mains to get the full 120v on the primary, but this jar only drops a few hundred volts so more voltage wouldn't help much.

hi, i like your plasma jar experiment.

can you tell me please, whats the schematic for the h.v. voltage source for this experiment. is it flyback,MOT, NST ? oh yes is your non frifge pump a multi stage evac.

thnks regds

@triggerhappy77707 cool vid none the less ..!

[triggerhappy77707]

@bonecrime I opened the ball valve at the end.

The vacuum leaked out? xD
