ملخص: A low temperature calorimeter with good energy resolution was developed for detection of energetic heavy ions. It consists of a doped germanium crystal as thermometer and a sapphire crystal as absorber, and is operated in a 4He window cryostat at temperatures ranging from 1.3 to 2.0 K. For 2.38 GeV 209Bi ions a relative energy resolution of [Delta]E/E = 1.8 x 10-3 was observed, most probably still limited by the energy spread of the incident ion beam.
