I hope it useful but enjoyable is a nice sidelight. Our first machine and FoFu-1 were designed by the same person, well, between the switches and the plasma load. Our first machine has been operating since 2006 so we have a few more years “practical” experience. We spent time burning contacts and revising. I know the pain all too well. My experience is limited to 0.5 MA so effects unique to larger machines are beyond my experience at the moment. I hope that will change next year.

Our interest is rep-rate PF operation so we had to focus on making the source run at 1 Hz. Contacts are a key part of the problem. We run our small PF at 10 Hz for hours so there is another level of problems that had to be addressed. This develop was evolutionary instead of revolutionary so it took us quite a few years to get everything running just OK. We hope to continue our PF work to make the source exceptional for our customers.
