so far i have assembled my vacuum pump to the chamber and added plugs for my electrodes, I am running neon sign transformer off of variac monitored by voltmeter, I have also hooked my scope to air coil to pick up EM, I wonder if this coil is even working?
Let me start now with the second run: I have replaced the anode and cathode with better insulated HV wire I cut from flyback transformer. Even with the better insulation it is still burning and getting peeled back as we go, also i had to go out and get hd camera to capture some of the effects i am seeing in the plasma, as my other cams are just showing white blotches. The images attached are all from the second run and have been balanced to see the colors in the plasma that i am seeing.
a)the first photo is the AC field with ambient pressure,i am guessing this just runs at 60hz.
b)The second photo shows the system forming and the electrodes glowing brightly also glowing is where the insulation is burning(t) off. you can also see where the corona is building between.
c)Third I took a snap shot of these red pulses that are forming randomly and only last for a split second.
d)As we proceed you can see the red pulses start to become more spuratic and after a bit of tweaking pressure and voltage we can see those domains form shells of light and dark, I am wondering what these shells are and how they are forming, all i can think of is cause of the AC field which is run at 60hz, but as the pink pulses form you can see them as arc breakdown activity on the oscilloscope, according to the scope the signal is running at MHZ, but if i measure the distance of 1red domain + 1 black domain = about 1-2mm, and if lambda=v/f then 2mm= 300ghz, is that last assumption correct? are any of these assumptions correct?
e) this next image the domains form and stabilize again these mysterious rings appear, again the scope goes crazy. can someone explain these rings and their frequency?
also, besides HV, is this dangerous, do i need to worry about xrays, or any other radiation?
