In my cap bank (see , I've managed to keep the impedance very low to the extend that my Pearson Current Monitors (a 410 & a 411) both reckon that my peak current is 2000+A (actually, at the moment I can't measure it as its too large).
Are there practical ways of limiting these sorts of currents dynamically, or should I just introduce a small high power resistor or series inductance - which seems odd after having gone to so much trouble to produce something with such low impedance.
With only 100V on the cap bank it is throwing a disc platter about 20 ft. I wouldn't want to be near it if it was fully charged.... I'm worried if I up the voltage my bricks will detonate...

How about some series inductance? The 'launch' coil will 'look' like inductance with resistance so say 10% of the launch coil inductance? (I've no idea !)
The most obvious solution (to me) would be to reduce the cap bank size.

Why not a higher inductance launch pad? Why bother upping the voltage at all if you're just going to waste power in a resistor? Higher voltage and a lighter load will help efficiency and effectiveness, like it does in power distribution.

Limiting current (apart from a resistor that is...)
