Design of a highly overmoded relativistic multiwave Cerenkov generator experiment

摘要

Experiments performed in the Soviet Union have demonstrated that the relativistic multiwave Cerenkov generator (MWCG) is capable of producing very high power centimeter and millimeter wavelength radiation at high conversion efficiencies. The MWCG configuration consists of a high power relativistic annular electron beam propagating in close proximity to a highly overmoded cylindrically symmetric cavity region which has two rippled wall sections separated by a constant radius drift space. The design of a highly overmoded MWCG experiment is described. The experiment is designed to operate at a frequency of 35 GHz with output power capability in the 100 MW range.
