Work on several maser projects is reported. These include solid state masers at 3 cm and at 21 cm, a solid state maser to operate at liquid nitrogen temperatures instead of liquid helium temperatures and an infrared maser. The application of maser techniques to radio-astronomic measurements and to high resolution spectroscopy of molecules is discussed. Studies of various materials, directed towards an elucidation of the properties of these materials for potential maser application are described. Continuing work on magnetron development and on the generation of Cerenkov radiation is reported. Experiments directed towards determining hyperfine structure measurements in various atoms are described. Finally the results of a continuing interest in the properties of the metastable state of hydrogen are described and a new experiment is proposed to determine the lifetime of the metastable state of singly ionized helium, a hydrogenic atom.
