RESEARCH ON MICROWAVE WINDOW MULTIPACTOR AND ITS INHIBITION.

Abstract

Titanium suboxide coatings for suppressing multipactor discharges at microwave windows were evaluated on alumina and beryllia ceramics. Coatings were applied by evaporating titanium in vacumm, sputtering titanium monoxide in argon, and spraying a suspension of titanium dioxide particles on to the window and subsequently heating in a hydrogen furnace. Measurement of surface resistivity appears to be the best method of controlling coating thickness. Evaporated and sputtered coatings of various thickness were tested and the range determined, which was the most suitable for multipactor suppression. Gases evolved during a multipactor discharge at an alumina surface were analyzed by a Diatron mass spectrometer. Results indicate that gas evolution is due to a protracted outgassing progess.
