Thanks for all the thoughts. We do need a fast rise—we want a turn-on ideally within 10 ns and definitely all firing within 100 ns. Each switch carries up to 250 kA with about a 1.5 to 1.8 microsecond rise time.
These are trigatron switches. Very simple design—described in the latest update from me. Here:

We’ll have more to report on in a couple of weeks when most of the switches have the copper inserts.
