As always, your home made equipment is extremely professional and rather state-of-the-art. Great pic's and progress. Do be careful of x-rays - 60 kV at over 35 ma will produce a very dangerous flux.

I built a 120 - 150 kV voltage multiplier and while it was all under oil, its nearby static effects convinced me to shut it down and place it in mothballs the first, and only time I charged it up.
Voltages in the 100 kV+ range can get rather flaky and difficult to safely shield. I also realized the accelerator it was to be tied to would produce just too dangerous of an x-ray flux; I went with my nearly done fusor instead.

Very nice setup Finn. I especially like your temperature monitoring arrangement for the typical problem areas. I’ll probably follow your lead here when begin my next phase of psu upgrades this summer.

Dennis,
Thanks for your kind words, and yes, radiation is a subject I will have to pay very serious attention to from now on. At present I am relying on below 30kV and the lead glas in the Lesker viewport.

Mark,

If you want to try the LLC topology, and need a PCB, then you know who to contact.

Cheers, Finn Hammer
