A 4-megavolt, 5-kiloampere pulsed-power high-brightness electron beam source
The REX machine at Los Alamos is being used to generate a 4-MW, 5-kA, 50-ns electron beam. The beam is produced by a planar velvet cathode, accelerated through a foilless anode aperture, and transported by an air core magnetic lens. Extensive measurements of the time-resolved (<1 ns) properties of the beam using a streak camera and high speed electronic diagnostics have been made. These parameters include beam current voltage, current density, and emittance for a single cathode/anode configuration. Results indicate beam brightness in excess of 10/sup 8/A/m/sup 2/-rad/sup 2/. Numerical simulations of the experiment have been performed with ISIS, a time-dependent PIC code, and are in good agreement with the measurements. This electron beam source is being considered as an injector to a linear induction accelerator and can be operated at higher voltages and currents as a stand-alone flash x-ray machine. 7 refs., 8 figs.
