High-power vacuum window in WR10

Abstract

Results are presented in this paper for fabrication and test of a WR10 waveguide window for use in ultrahigh vacuum at 91.4 GHz. Low-power bench measurements are compared with analytic and simulation results. Operation at /spl ap/4-kW peak power, duty factor 10/sup -6/, and 10/sup -9/-scale vacuum is noted.
