摘要：
An experimental study on the propagation of a sheet electron beam of energy similar to 200 keV, current similar to 80-250 A, and pulse duration of similar to 100-150 ns through a planar five-period electromagnetic wiggler has been carried out as a part of the development of a pulsed, high-power mm wave free-electron laser. Beam focusing is observed for peak wiggler magnetic fields up to 2.5 kG, and enhancements in propagated beam current efficiencies by 40%-65% are found for different values of the initial beam current.
