The main goal of the University of Maryland's gyroklystron project is to develop an efficient, high power, high gain, phase controllable amplifier at 10 GHz. While peak powers of several hundred megawatts are ultimately of interest, our initial experimental design values include 30 MW of output power in 1 μs pulses with a gain in excess of 50 dB. The 30 MW power level represents an enhancement of almost three orders of magnitude over the current state-of-the-art in gyroklystron amplifiers.1,2 This enhancement will be achieved by going to high beam energies (γ ≈ 2) and overmoded cavities TE001. Outlined in this report are the steps being taken to realize our goal.
