摘要：
A high-average-power FEL amplifier operating at submillimeter frequencies is under development at the University of Maryland. Program goals are to produce a cw, approximately 1 MW, FEL amplifier source at frequencies between 280 and 560 GHz. To this end, a high-gain, high-efficiency, tapered FEL amplifier using a sheet electron beam and a short-period (superconducting) wiggler has been chosen. Development of this amplifier is progressing in three stages: 1) beam propagation through a long length (approximately 1 m) of a short-period (lambda-w = 1 cm) wiggler, 2) demonstration of a proof-of-principle amplifier experiment at 98 GHz, and 3) designs of a superconducting tapered FEL amplifier meeting the ultimate design goal specifications.
