Characterization of the rod-pinch diode at 2 to 4 Mv as a high-resolution source for flash radiography

Abstract

The ASTERIX generator is used to evaluatate the rod-pinch electron-beam diode as an intense source of x-rays for high-resolution, pulsed (30- to 40-ns FWHM) radiography at peak diode voltages of voltages of 2.4 to 4.4 MV and peak diode currents of 55 to 135 kA. At 4 MV, tungsten anode rods of 1-mm or 2-mm diameter produce on-axis doses at 1 meter of 16 rad… (More)
