Ken,

Yes, I've shrunk quarters in the past too, had 10 kV -at- 200 uFD
(10 kJ). It made one heck of a boom and blew copper shrapnel
at near ballistic velocities and an awesome shockwave that would
dent up the 1/8" thick steel walls of the containment vessel tank.
It was pretty scary and I decided to preclude further quarter
shrinking at least until i could get some better facilities/equipment
for it. Right now the big Marx generator is admittedly a "pipe
dream" for the time being but I would someday like to take on
this monumental project and may end up trying to build it sub-
merged in oil.
