Development update of a 10 MW, 91 GHz gyroklystron

Calabazas Creek Research, Inc. (CCR) is funded by the U.S. Department of Energy to develop a high efficiency gyroklystron amplifier for W-Band linear collider applications. This research supports an international effort to design the next generation of linear electron-positron colliders with anticipated center of mass energies of 0.5 TeV and beyond. In particular, this program supports development of a W-Band accelerator now underway at the Stanford Linear Accelerator Center. CCR is developing a 91.392 GHz gyroklystron to produce 10 MW of RF power with efficiency greater than 40% and a gain of 55 dB. Achievement of 10 MW of peak power would advance the state of the art for W-Band amplifiers by two orders of magnitude and potentially lead to other applications, including land- and ship-based radar, medical accelerators, and materials processing.
