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.
