Jt. Donohue et al., Power generation in a resonant cavity using a beam bunched at 35 GHz by a free electron laser, NUCL INST A, 445(1-3), 2000, pp. 307-312
An intense beam of relativistic electrons (800 A, 6.7 MeV) has been bunched
at 35 GHz by a free-electron laser, in which output power levels exceeding
100 MW were obtained. The beam was then extracted and transported through
a resonant cavity, that was excited by its passage. Microwave power levels
of 10 MW were extracted from the cavity, in reasonable agreement with a sim
ple formula which relates power output to known properties of the both beam
and cavity. (C) 2000 Elsevier Science B.V. All rights reserved.
