    Hello all. Wondering if anyone can help.
    I’m considering building a plasma containment experiment. I plan to use my Voltage multiplier that delivers about 100kv. I need this to generate a substantial electric field and plasma arc within the reaction chamber. What I want to do is then drop a high current source ( DC 400A / 16v ) onto the pilot plasma arc much in the same way a plasma arc cutter works. However.... (and this is the bit I am stuck on) do I configure the circuits so that the 100kv source doesn’t route the wrong way through the high current 400A supply? I assume the 100kv is going to find it easier to route back through a rectifirer/ transformer to earth than discharging through the reaction chamber. Or once the plasma is established, maybe the plasma arc is of suffiently low resistance that it is the more attractive route for the 100kv. As I said previous, plasma cutters work via this 2 circuit process but I’m not entirely sure how this is achieved.
    Any help greatly received.
