  • Abstract
    The negative-polarity rod-pinch diode is being developed and tested on the RITS-6 accelerator to expand radiographic capabilities. High current densities at the tip of the rod anode generate a plasma which expands at a rate of 2-4 cm/μs. Images of visible light captured with a high-speed intensified charge-coupled device camera show the development and expansion of the plasma.
