Abstract

Summary form only given. Theory and simulation of the 2-D electron dynamics in a magnetically immersed foilless diode are presented. The diode consists of a cylindrical needle point cathode and flat anode, all immersed in a large (/spl sim/20 T) solenoidal magnetic field. High-brightness electron beam experiments utilizing such diodes have been conducted at Sandia National Laboratories on the Hermes III accelerator. Power is delivered to the diode load via a magnetically-insulated-transmission-line (MITL). The nominal e-beam parameters in these experiments are 10 MeV, 40 kA, 1 mm radius, with pulse lengths of order 30 ns.
