Abstract

Summary form only given. Results from numerical simulation and analytic theory of magnetically immersed diode behavior on the United Kingdom´s Atomic Weapons Establishment (AWE) Superswarf accelerator are presented. The immersed diode consists of a cylindrical needle point cathode immersed in a strong /spl sim/10-20 T solenoidal magnetic field. The anode-cathode (A-K) accelerating gap is held at vacuum and is /spl sim/5-10 cm in length, with the anode/target located at the mid-plane of the solenoid. Typical accelerator parameters are 5-6 MeV and 40 kA.
