Abstract :
The Negative-polarity Rod-pinch (NPRP) diode is being developed and tested on the RITS-6 accelerator to expand radiographic capabilities. Experimental results include shots where the diode impedance is relatively constant and the x-ray dose is as high as 175 Rad@1m with a 2.5-mm source spot size. Other shots have a rapidly decreasing diode impedance and much lower X-ray dose. Data presented here include measurements of beam current, dose rate, forward and backward directed dose, and x-ray source spot size.
