Abstract
A massive bolometer with a 760 g TeO2 crystal as energy absorber, the large st employed underground, has been realized and operated in the Gran Sasso U nderground Laboratory for gamma- and alpha-ray spectroscopy. A new system o f mechanical suspensions was implemented to reduce vibration and thermal no ise, and special care was put to the read-out electronics. As a consequence the FWHM resolution for high-energy gamma-rays became comparable to that o f Germanium diodes. The 4.2 keV average FWHM resolution for the 5407 keV li ne is the best ever obtained for alpha particles with any type of detector. (C) 2000 Elsevier Science B.V. All rights reserved.
