Well now that I have actually got this thing to work I need to fix a coulpe things. First of all the flow regulator has to go. I just assembled a pressure regulator from pieces I had lying around and will give that a shot when I get home. The mirror alignment issue is quite annoying. I am going to build a mount from steel and strap the tube down by the mirror insulators. I am also going to try using spring loaded mirror mounts to try to keep a more constant pressure on them and also reduce the sensitivity of the screw adjustment. Third I havn’t pressure tested the system with water yet. I just picked up the final pieces I need to finish that part and will try it soon.
I have called about getting a proper sized transformer for this tube so I will be able to run it at it’s full 60mA capability. I am also trying to source some high voltage rectifier diodes to try running this on DC, I already have a suitable sized filter capacitor bank rated at 30kV for the job aswell.
I have a variac which will allow me to adjust the output. I’m not sure how well adjusting the voltage with a variac will work while still runnning AC. The arc seems to just barly start at 15kV and with a reduced voltage and a zero cross it may not restart. Running DC should be fine although, once the arc is initiaded the DC current should keep the path ionized as the voltage is dropped.
