Abstract: 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, ~ 1 MW, FEL amplifier source at frequencies between 280 GHz and 560 GHz. To this end, a highgain, high-efficiency, tapered FEL amplifier using a sheet electron beam and a short-period (superconducting) wiggier has been chosen. Development of this amplifier is progressing in three stages: (1) beam propagation through a long length (~ 1 m) of short period (Aw = 1 cm) wiggier, (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.
