Development of a 1 microsec, 40Hz, X-Ray Source

Abstract

We are developing a 1 cm diameter, 1 microsecond, 300 keV, 1 kA repetitive pulsed electron beam diode to be used in a linear x-ray source. The diode is required to operate from a single pulse mode up to 40 Hz. A single pulse, double x-ray source has been developed and tested. Each source produces a 1 microsecond electron beam with energies up to 300 keV, 1 kA for each of the two sources. The electron beams impinge on 5 mil tantalum converters to make the x-rays. The x-rays are produced in field emission diodes powered by a single PPT, a pulsed transformer and a capacitive pulse forming network (PFN).
