Design of a 100 MW, 17 GHz second harmonic gyroklystron experiment

Abstract

At the University of Maryland, we are exploring the suitability of gyroklystrons for linear collider applications. In this paper we discuss the design of a two-cavity, coaxial gyroklystron that is designed to produce over 100 MW in 1 ps pulses at the second harmonic of the cyclotron frequency. We detail modifications that will be required of our test facility, present the simulated performance of a 400 MW, 500 kV single-anode Magnetron Injection Gun, and describe the design of the coaxial microwave circuit.
