Abstract

URSA Minor is a 21-cavity Linear Transformer Driver (LTD) that has been built to evaluate LTD technology as a driver for flash radiography diode research. The LTD has been assembled and tested with initial testing being conducted at ±75 kV charge. In this configuration the generator has produced 1.7 MV on a 30-ohm MITL when driving an electron beam diode. Diagnostics during initial testing include cavity voltage, MITL currents, x-ray dose using TLDs, and x-ray dose rate using PIN diodes.
