Further Studies of the NRL Collective Particle Accelerator VIA Numerical Modeling with the MAGIC Code.
Abstract
The 2-D. electromagnetic, relativistic simulation code, MAGIC, was used to investigate the detailed physics associated with the operation of the NRL CPA testbed experiment. Code results contradiicted the original conclusions drawn from the experimental diagnostics in that the central beam always propagated with a current of 1-2kA in the numerical simulations while the experiemntal probes failed to detect that beam's presence in dual-beam mode of operation. Since 1-2kA was on the sensitivity threshold of their instruments used in the experiment, there is no reason to disbelieve the MAGIC results. This work argues in favor of a renewed CPA effect with improved diagnostics. Additional keywords: Magic computer code; Magic(Magnetic Insulation Code); Foilless diode; Relativistic electron beam.
