Experimental SGEMP Results Using Electron Beam Injection

This paper presents results from a SGEMP/IEMP phenomenological experiment designed to explore the behavior of an axially injected electron beam Within a cylindrical test chamber, Data on two different injected beams characterized by mean electron energies of 40 and 60 keV and pulse durations of approximately 80 and 30 nsecs full width at half maximum (FWHM) respectively are presented. These data include internal local magnetic fields, transmitted current and transmitted current distributions, localized wall segment currents and radial current densities as a function of pressure. The pressure range extends from -1¿ to over 10 torr.
