The study of microwave breakdown at high pressures continued and material for the revised handbook on the power handling capabilities of high power waveguide systems is presented. The breakdown measurements of air, SF6 and Freon 12, reduced to absolute values, satisfactorily extend low pressure measurements. A discussion is included of the calibration of the cavity used in the breakdown measurements. The cavity was calibrated to relate the electric field strength in the center of the cavity to the power measured in the transmission line. Absolute breakdown curves are given for the various gases discussed and these results are compared to the work of others. Results are given of breakdown measurement of several waveguide components.
