Title: Wiggler focused relativistic sheet beam propagation in a planar free-electron laser configuration
Author: Radack, D.; Booske, J.; Carmel, Y.; Destler, William
Abstract: The propagation of a relativistic sheet electron beam through a spatially periodic magnetic field (wiggler) has been studied experimentally. The wiggler serves two purposes; it provides beam focusing as well as the magnetostatic pump for the free-electron laser (FEL) interaction. Experiments conducted to study sheet beam generation and propagation in a short-period (1 em) planar wiggler are presented. A 500 keY, 7 A sheet electron beam was propagated through a 3.2 mm waveguide with negligible losses due to intercepted current. In addition, the first observation of wiggler-induced radiation was obtained from the sheet beam FEL in a short-period wiggler oscillator configuration.
