The Radiographic Integrated Test Stand (RITS) accelerator was built as a test bed for research and development of pulsed power drivers and radiographic diodes. The RITS-3 acceleratory has been upgraded from three to six inductive voltage adder cells. The new RITS-6 acceleratory is designed to deliver 11 MV, 125 kA, 60-nspulses for flash X-ray radiography source development.
