Investigation of Atomic Physics and Frequency Stability with a Croygenic Hydrogen Laser.
Abstract
Research has been conducted 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 (DJ3RM) may have frequency stability comparable to that of a room temperature hydrogen maser but in a smaller, more robust, and lower cost package.
