High average power rf window study
WebAbstract A study has been performed to design a waveguide vacuum window capable of propagating >1 MW average power operating at 500 MHz. This would extend current technology by about a factor of 2 in average power for stand-alone windows, made possible by advances in available ceramic size and quality.
