Abstract

Summary form only given. The results of a study performed by CPI for CERN are described below. The purpose of the work was to design a pulsed 30 GHz, 50 MW gyroklystron amplifier to be used for testing and conditioning Compact Linear Collider (CLIC) mainline accelerating structures. The specifications for the amplifier are listed. The technical risk factors and achievable performance for several distinct configurations, including coaxial and cylindrical cavities interacting at the fundamental and second harmonic of the cyclotron frequency, were investigated in the study. Following detailed physics designs of several different circuits and electron guns, a fundamental TE₀₁₁ coaxial mode configuration was selected as the most likely to achieve the specifications. Design details and performance predictions for this configuration are given.
