Beam Dynamics in Stripline Linear Induction Accelerator
Abstract
Stripline (parallel plate transmission line) pulsed power modules have been considered for application to advanced high current linear accelerators. Some advantages of the stripline designs include compact size, easy maintenance, and most importantly, the small number of switches required (one switch per 2 MeV). The principle drawback of stripline designs is that they impart a net transverse force to particles in the gap. This is shown to result in randomized transverse momentum, and net, constructive transverse guiding center motion. In this paper, a semi-quantitative analysis of several facets of the problem is presented. Section II deals with the zero-order orbital mechanics of particle motion in the accelerator. The important result is that net guiding center motion is more important than temperature increase. In Section III, the magnitude of the asymmetric magnetic field, which drives the beam off axis, is calculated in an approximate fashion for several stripline configurations. In Section IV, the overall importance of the problem, and the beneficial results of modifications to the stripline design are presented.
