Oh, I know, and the output is possibly almost more dangerous than the
raw 7KV (as any body parts may not blow fuses on the output).
As I posted in the beginning, this would be done with interlocks on
everything, meters on all the caps, as well as neon flashers in case a meter
fails, and shorting relays that operate when the case is opened, in case
Currently looking at IGBT's that look almost fast enough.
Then again, I would need at least 30 of them in series/parallel, which
Substantially less sticker shock than hollow-state devices though.
I'd be aiming at using them at no more than half their working voltages, as
I hope the initial expense is outweighed by lowering the likelyhood of
