Abstract
Progress in studies of a millimeter-wave free electron laser amplifier based on a small period planar wiggler and a sheet electron beam is r eported. Successful propagation of a 15 A sheet electron beam has been accomplished through a 56-period wiggler magnet (B(w) = 5.1 kG, lambd a(w) = 9.6 mm); this was made possible in part by employing a novel me thod of edge focusing using offset pole pieces. Status of a 94 GHz pul sed amplifier experiment is discussed. Design parameters are presented for a 150 GHz, 5 MW cw amplifier with peak rf wall heating approximat ely 1 kW/cm2; such an amplifier may be relevant to plasma heating in f uture magnetic fusion experimental reactors.
