A Characterization of Tri-MeV as a Flash Radiography Device

ORAL

Abstract

The Tri-MeV electrostatic electron accelerator can deliver a 3 MeV voltage pulse with a current and duration of 30 kA and 20 ns. Up to now available literature $[1]$ suggests the smallest radiographic spot size the Tri-MeV system can produce is 0.8 mm in diameter, being the full width half maximum (FWHM) of the source, with a duration of 19 ns and a dose of 1.2 rad one meter from the source. A recent series of experiments with Tri-MeV have revealed its capability to produce an x-ray burst 5 ns in duration, a dose of 0.7 rad at one meter with a 720 um FWHM x-ray source diameter. In this presentation I will discus x-ray source as observed in this series of experiments.\\ $[1]$ Peter R. Menge, David L, Johnson, John E. Maenchen, Craig L. Olson, and Dean C.
