NST Star Mode

This is the best star I could muster up with a 15kV NST. The diff pump pulls way too deep of a vacuum so constant throttling was required to keep the star from extinguishing. Being a shunted power source the maximum voltage I could attain was just over 8kV. The star in the pic was at about 43 mTorr. Any lower and the NST was useless at maintaining a plasma. I’ll be getting the X-ray transformer assembled over the next few weeks.
