Abstract:

Absolute electron yields from tantalum, molybdenum, copper and aluminum have been measured for several bombarding geometries. The photon spectra used were derived from filtered bremsstrahlung generated in a tungsten anode at 50 kV, constant potential. The electron spectra were measured by a cylindrical electrostatic analyzer with a secondary emission detector. The spectra exhibit both Auger and scattered photoelectrons. The electron current densities arising from these spectra constitute source functions for vulnerability studies on systems exposed to internal electromagnetic pulse IEMP effects arising from nuclear environments.
