Recent theoretical modeling of rod-pinch RP diode behavior has been carried out for diode voltages of up to 10 MV. The theory, consistent with experimental results on Asterix at up to 6 MV, predicts that, above 4 MV, x-ray production in the forward direction is more efficient for negative-polarity operation than positive-polarity operation. Here we report on negative-polarity RP diode experiments at 5 MV on RITS-3, an inductive-voltage-adder IVA generator with vacuum flowing electrons. Extensive analysis of the electrical and x-ray data combined with numerical simulation suggests that the diode operation is consistent with the modeling.
