Abstract:

Low temperature research, High frequency. Identifiers Optical maser, Infrared maser, M-Band. The 10 cm maser-radiometer is being used at the Naval Research Laboratory, initially for measurements on the planet Saturn. Experiments are described using an M-band radiotelescope at Columbia in an attempt to measure sextuply ionized nitrogen in the suns corona. Developments in the production of a microwave cavity charged-particle-detector are discussed. A detailed discussion of several major maser projects is given, including recent work with optical masers. A number of projects dealing with microwave and atomic beam spectroscopy are described. Progress in studies of various atomic properties by means of high sensitivity optical double resonance methods is reported, including work on several isotopes of cadmium. An experiment to determine the lifetime of metastable helium ions is described in detail. Author
