Numerical Simulation of Relativistic Electron Beam Generation with a Foil Diode
Abstract
Atmospheric propagation experiments at the Air Force Weapons Laboratory utilize a 150 KA, 6 MV relativistic electron beam produced by field emission in a foil diode. To characterize the beam for the experiments requires an understanding of beam formation in the diode. To this end CCUBE, a sophisticated two-dimensional, time dependent, particle-in-cell code developed at Los Alamos National Laboratory, has been used to simulate electron beam generation in a foil diode. Simulation results for two different cathode tip geometries are discussed. Comparisons with experiment are made.
