TIME and TEMPERATURE STABILITY of SILVER-COATED CERAMICS for HYDROGEN MASER RESONANT CAVITIES

Edward M. Mattison, Robert F.C. Vessot

Abstract:	We have investigated the dimensional stability, as a function of time and temperature, of silver-coated glass-ceramics typical of those used in hydrogen maser resonant cavities. The measurements show that (a) the stress in the silver coating decreases with time at a rate proportional to the initial coating stress, and (b) the variation in stress with temperature is proportional to the initial stress, and decreases with time. Observations indicate that the coating stress can be relieved by precooling the materials.
