摘要：
As a first development of a bolometric dark matter detection experiment, preliminary radioactive background measurements, down to 3 keV, are performed using a 24 g sapphire crystal cooled at 55 mK. The experiment is operated in a deep underground laboratory (Laboratoire Souterrain de Modane) in order to eliminate the cosmic ray background. Due to the low energy threshold it is shown that, for low mass dark matter particles (less-than-or-equal-to 10 GeV/c2), bolometers are potentially better than the conventional semi-conductor (Si, Ge) or scintillating (NaI) detectors.
