I have a drawer full of 15kV and higher, glass vacuum relays that
I've accumulated over the years. They can handle 10s of amps, and
thus could conceivably be the switching basis for a passive circuit
to create our 10kV 1us ramp. However, we need a repeatable ramp,
hopefully without significant time jitter, since we'll be signal-
averaging the data from thousands of scans. We will be digitizing
the voltage ramp, so it's possible we could adjust the time bins
after the fact. I'm not sure about contact bounce on my HV relays.
