Re: Marx Generator Success!
Original poster: "by way of Terry Fritz <teslalist-at-qwest-dot-net>" <dhmccauley-at-spacecatlighting-dot-com>
Currently I'm using one side of a 12kV/30mA NST which first runs through a
2-stage Cockroft-Walton multiplier.
So at 120VAC input voltage to the 12kV/30mA NST on one leg that gives me
6kVAC/30mA to the input of the CW multiplier which
in turns gives me approximately 30kVDC output of the CW multiplier (no load
voltage).
If I set the input to about 70% on variac, rep rate is about 2-3Hz. If I
set to 100%, rep rate is about 0.5 to 1Hz. So the marx generator is running
a bit on the low
side. Tomorrow I'll hook the input to the marx generator up to my hv
divider and verify exactly what voltage I'm loading it with.
