Free Electron Lasers Based on High Current Electron Beam

Abstract

The stimulated radiation generation of intense electron beam with 1 MeV energy and current to 13 kA has been investigated. The radiation to 20 MW power in 7 + 13 mm band with the pump by helical magnetic field of the undulator and to 6 MW in 3 cm band with the pump of 10 cm electromagnetic wave has been received. The dependences of output power on pump field, transverse focusing magnetic field and interaction field length have been studied.
