Abstract

We report on a calorimetric particle detector consisting of an 18.3 g silicon crystal and an iridium superconducting phase transition thermometer. The cryogenic calorimeter and the associated apparatus are described in detail. The pulses from irradiation with an α-particle source have a large unexpected overshoot in addition to the component expected from a naive thermal model. The pulse height spectrum displays an energy resolution of 1% FWHM at 6 MeV and good linearity. The noise, electrothermal feedback, and position dependence are discussed.
