A high-resolution spectrometer based on low-temperature calorimetry             has been developed with the use of a composite bolometer.  The low              specific heat at < 1 degree K allows small amounts of energy deposited          by single alpha and beta particles, or X-rays, to be detected as                proportional temperature pulses.  The initial motivation was a new              type of neutrino mass measurement.  Applications will be much broader,          including X-ray astronomy, high resolution nuclear spectroscopy,                material testing (e.g., energy loss measurements of particle beams              traversing matter), determination of specific heats at low                      temperatures, and astrophysics.  This project will seek to extend this          work from 1 degree K to ~ 0.05 degrees K, where a thermodynamic                 resolution gain of ~ 103 to a few electron volts is predicted.                  Factors affecting detector resolution and time constants will be                studied, and the use of the calorimeter exploited with spectrum                 measurements of external and implanted radioactive sources.
