Precision Measurements with Hydrogen and Rubidium Masers

Abstract

This AASERT grant supported Ph.D. thesis research on two new atomic clocks: the cryogenic hydrogen maser and the double bulb rubidium maser. The cryogenic hydrogen maser (CHM) operates at low temperatures, and may provide frequency stability that is one to three orders of magnitude better than a room temperature hydrogen maser because of greatly reduced thermal noise and larger signal power. The double bulb rubidium maser (DBRM) may have frequency stability comparable to that of a room temperature hydrogen maser but in a smaller, more robust, and lower cost package.
