Single circuits generate nuclear reactions

yes, you are dropping most of your gate drive voltage across the 10 Ohm resistor because of the 1 Ohm resistor shunt. remove the 1 Ohm and it should work.

excellent, thanks poynt99. i'll try that tonight, any problems i'll let you know.

[poynt99]

you still might need a path to ground on the emitter though, so driving a fet with one transistor is not the best. maybe a 100Ohm to ground.

you might want to check into fet drivers

I have not seen any sign of beta radiation from a carbon rod subjected to a  high energy capacitor discharge with or without a magnetic field in either direction along the axis of the rod.

The rod used is a 7 mm welding carbon. The distance between the electrodes on the carbon rod was initially 230 mm and then a second set of tests were done with 60mm between the electrodes.
A thin window Geiger counter tube was used and checked to see if it could detect 1.3 Mev beta radiation from the K40 trace in potassium chloride, which it did.

The capacitors which provided the impulse were 8 parallel connected 1000 microfarad 400 volt capacitors switched through a large thyristor. The pulse energy was varied from 40 joules up to the maximum 640 joules with the applied voltage starting at 100 volts for the first impulses  and finishing with 400 volt for the final impulses. Several impulses were tried through the carbon at each voltage setting without a trace of beta emission.
Magnets placed with the field in either direction along the rod had no effect.
The impulses from the Geiger counter were viewed on a storage scope so the average count was clearly visible.

Same problem I found.  I have been laying low till I get in a "Pure" rod.  My large low ESR Cap. arrived yesterday.  It is a honker.  4200uf, 500VDC rating.  Will make up a simple circuit of several high power IGBT's and a series bus system to switch this Cap.  No Hurry here, it seems we all are missing something so time will tell.
