Abstract

A simulation is performed of a spatially extended free-electron maser (FEM) of planar geometry based on the use of a three-dimensional distributed feedback mechanism in so-called three-dimensional Bragg structures. The possibility is studied of creating a FEM of this type in the W-band, based on the U-2 high-current explosive emission accelerator at the Budker Institute of Nuclear Physics, to form a sheet electron beam of 1 MeV/140 kA/10 μs with a cross section of 1 × 140 cm. The possibility is shown of creating a stable regime of narrow-band generation in the FEM at the optimum parameters of an electron efficiency of ∼18–20% and a record output power of up to ∼20 GW level.
