Paper Abstract

The planar orotron is a promising new device which is capable of producing millimeter and sub-millimeter radiation of moderate to high power. The orotron resonator is a slow wave structure consisting of a rectangular metal grating which is opposed by a planar metal boundary. When an electron beam grazes the grating surface, it can couple to travelling waves which then amplify and leave the resonator in the direction of the beam. For a given grating design, a unique and continuous set of frequencies may be represented by the travelling waves, making the planar orotron a remarkably tunable source. Details of the theory of operation are presented, as are experimental results of one design which has produced up to 2 kW of power in the 30 to 40 GHz range using beam voltages under 20 kV.
