Abstract

The free-electron-laser experiment in the milli-meter-range by the coherent radiation emitted from an electron bunch is reported. With a 7MeV rf-linac, the spontaneous emission of 20W has been observed. The oscillation experiment has been performed by superimposing this radiation in the resonator. Power of 16W was observed at wavelength of 2.73mm.
