The objectives of this contract were to develop atomic hydrogen masers based upon novel concepts of cavity stabilization and new designs of the maser physics unit to provide improved stability and environmental isolation as well as a reduction in size,, weight, cost and power consumption. First, new maser designs were developed which implemented electronic cavity frequency stabilization using the cavity frequency switching technique. These new designs also incorporated a novel cavity assembly which is smaller than that used in past masers and new quadrupole state selectors based upon concepts described in the cited referfences. Then two representative hydrogen masers were constructed and tested and experiments were performed to optimize the electronic systems.
