At the University of Maryland, the have been developing gyroklystrons as potential drivers for future linear colliders. In this paper we present the results of our high-power testing of a 3 cavity coaxial gyroklystron circuit which is designed to produce over 80 MW of power at 17.136 GHz. We also present designs for a tube with radial output power extraction and our designs to interface our gyroklystron with a 17.136 GHz accelerator structure. Finally, we summarize the results of our scaling studies of gyroklystron systems from X-Band to W-Band. We use scaling laws to show that both the electron gun and the microwave circuit can be scaled over a wide frequency range with an output power that is proportional to the output wavelength. Simulations that verify the results of these scaling laws have been performed and the results are discussed. Limitations to the scaling are also described.
