A new type of high-selective Bragg resonator having a step of corrugation inside the interaction region was used as a microwave system for a free-electron maser (FEM). Using a LINAC LIU-3000 (1 MeV/200 A/200 ns) to drive the FEM oscillator, a single-mode single-frequency operation was achieved at a frequency of 30.74 GHz with an output power of about 50 MW, which corresponded to a record efficiency of 35% for a millimeter wavelength FEM.
一种新型的高选择性布拉格谐振器被用作自由电子激光器（FEM）的微波系统，该谐振器在相互作用区域内有一个波纹台阶。使用直线加速器LINAC LIU - 3000（1 MeV/200 A/200 ns）驱动FEM振荡器，在30.74 GHz频率下实现了单模单频运行，输出功率约为50 MW，这对应于毫米波波长FEM创纪录的35%的效率。
