yea that's the pulse cap. 450 pulses/second max. I'm going to need a big switch for it though, so I have to think about how to achieve that goal.

Well, it would make a great DRSSTC tank capacitor... :P

but where would I get a switch capable of 18KV? I dunno what the current from that thing would be, it has to be horrendous. I'd probably have to go with a rotary unless I can find a SF6 switch capable of switching 20J somewhere.

110nF is quite low for DRSSTC's, except maybe smallest ones, while 18kV is quite high voltage. (It would look silly in a coil size of mjolnir).
It may work in longer bursts, although everybody seems to consider high characteristic impedance less efficient.

Depending on it's voltage reversal rating, you may actually be much better to use it for a SGTC.

If it can handle such operation and be efficient, you can use two outer terminals for a killer 36kV 27.5nF capacitor. Good for like 20kV at 4kW, maybe even more depending on it's reversal rating.

Do you have any information on internal constrction of that cap? What dielectric does it use?

They don't specify the dielectric, but it is a pulse cap and the make is BYCAP INC. 2x .055uF 18kvdc 450pps max. That's all I know.

My latest chemistry toy, just tested today. It's a two-stage quasi-continuous reflux distillation aparattus, all borosilicate, teflon, corrosive rated stainless pressure/vacuum gauges, and fluorosilicone based stopcock grease.

Sweet setup you have there. The only trouble with second hand labware, and I have a lot too, is you don't know what has been in it, so you don't know how clean it is. This can be real problematic depending on what you want to do. Flushing with Nitric would probably be a good idea, and BC would probably have some suggestions too.
Chromic-Sulphuric used to be used a lot, but the Cr 6+ is a pain to dispose of properly.
