摘要：

With simultaneous measurement of the temperature signal and the scintillation light of a CaWO4 absorber crystal, it is possible to reject the gamma and electron background in the Cryogenic Rare Event Search with Superconducting Thermometers experiment. In order to understand the different events from various particles correctly a neutron calibration experiment and other tests are necessary. Using an existing accelerator facility these tests will be performed above ground. For such an experiment, a detector with good stability at high count rates is necessary. The detectors used in the Gran Sasso Laboratory are equipped with W-thermometers. They show long decay times and need active stabilisation and therefore are not well suitable for experiments with high count rates. We report on developments and first results on detectors based on Ir/Au-thermometers in electrothermal feedback mode. (C) 2003 Published by Elsevier B.V.
