密集（n = 1012 cm−3）、温和相对论性（1.8<γ<3）电子束与圆柱形介质内衬波导的相互作用产生了频率范围为150-310 GHz的可调谐微波辐射，估计功率输出在150 GHz时为500 kW，在310 GHz时为10 kW。所测得的输出频率与衬介质波导的TM 01模的相速度与电子束速度同步的频率一致。
The interaction of a dense (n∼1012 cm−3), mildly relativistic (1.8<γ<3) electron beam and a cylindrical, dielectric lined waveguide has produced tunable microwave radiation in the 150–310 GHz frequency range with an estimated power output of 500 kW at 150 GHz and 10 kW at 310 GHz. The measured output frequency agrees well with the frequency for which the phase velocity of the TM01 mode of the dielectric lined guide is synchronous with the electron beam velocity.
