A good explosive should achieve 3,000 m/s, assuming 10 cms diameter we have 30 microseconds, about the same as yours. I don't actually know the principle behind the device, but I assume the explosive produced a plasma and that allows kinetic energy to be turned into EM as it move through the magnetic field. If so, I would be tempted to detonate the explosives by using them as the spark for the induction coil, and the explosive debris should be highly conductive.

FYI, pulse in English is clap. > 5) Can you suggest any other design optimisations? > > I am willing to provide funds for quality advice if you can provide > evidence of your expertise. You could wing it after brukan the time constand formula--hook up a power LC (or R/C) tank to a quarter shrinker.
