Abstract

Summary form only given. The Naval Research Laboratory has recently initiated design and development effort to develop a high average power GHz gyroklystron. The amplifier will operate in the TE/sub 01/ mode the fundamental cyclotron harmonic. Because of the critical dependence of gyro-amplifier efficiency on the electron be quality, a key element in this effort is the gun design. The overall goal of the gun design work is to account for various contribution factors to beam velocity spread and to minimize the beam sensitive to their influence. In addition to the beam spread resulting from the usual beam optics, these factors include cathode surface roughness and misalignments.
