Response of bolometric cryodetectors to energetic heavy ions

Conference:

Abstract

The response of bolometric cryodetectors to the impact of energetic heavy ions was investigated for the first time. For that purpose two types of detectors, one on the basis of a heavily doped germanium crystal serving both as absorber and thermistor, and the other a composite bolometer consisting of a germanium thermistor and a sapphire absorber, were bombarded with heavy ions (Ne, Ar, Xe, Bi) in the energy range 3.6 MeV/u < E < 12.5 MeV/u. In the first case we observe complex energy spectra, the structure being dependent on temperature, position of impact and various other parameters. Narrow gaussian peaks are observed for the composite bolometer. For 2.4 GeV {sup 209}Bi ions an energy resolution of {Delta}E/E = 1.8x10{sup -3} is observed, most probably limited by the energy resolution of the incident ion beam. This result already represents a considerable improvement for such a heavy ion as compared to conventional solid state detectors and ionization chambers. (orig.).
