Dr. Jaffe and his group have designed and constructed a                         spectrometer receiver for the 500.900 Gigahertz frequency band.                 The receiver consists of a cooled, open.structure Schottky diode                mixer coupled quasi.optically to the telescope and to an                        optically pumped laser local oscillator.  This grant will be used               to package the system for use on the California Institute of                    Technology Submillimeter Observatory telescope in Hawaii.                                                                                                       The receiver built by Dr. Jaffe can make a valuable contribution                to many astrophysical problems.  These include studies of warm,                 ultra.dense gas in the immediate surroundings of massive                        protostars, observations of warm quiescent gas including studies                of CII/CI/CO interfaces in clumpy molecular clouds, and                         investigations of hot molecular gas in protostellar flows.
