Dave,
I am still in the info and hardware gathering stage. I have a circuit
designed and it is a grounded cathode system. The thyratron I am using
for the earliest tests will be the KU-25 Hydrogen Thyratron. It can
handle megawatt pulses with ease at 15,000 volts -at- ~300 amps. I tend to
be very slow and methodical in researching things. I am looking at the
old resonant charging methods of the older radar systems for insights.
As you know the H2 thyratrons are incredibly expensive and I don't want
to blow my few examples obtained from hamfests up needlessly. The grid
pulse circuitry can be tricky but may be worth the extra effort. As it
stands now, I will have to wind my own custom pulse transformer for this
circuit.
