RESEARCH ON MICROWAVE WINDOW MULTIPACTOR AND ITS INHIBITION

Abstract

Multipactor discharges at beryllia and alumina windows were suppressed by both sputtered titanium suboxide coatings and evaporated titanium coatings. Tentative thickness limits in terms of sputtering current and time were established for titanium monoxide coatings sputtered in argon. A range of coatings sputtered in mercury were satisfactory but thickness limits have not been determined. Lighter coatings will suppress multipactor only after a period of operation. Coatings have been tested at 2700/Mc/s up to equivalent transmitted powers of 40 Mw peak and 320 kW average without failure. Power has been limited by arcing at the metal-dielectric seal rather than by multipactor discharges.
