The authors have developed a 60 g particle detector which utilizes both the ionization and the photons produced by a particle interaction. Six NTD Ge thermistors are attached to a pure germanium crystal which has implanted contacts for drifting charge. The authors have operated our detector at 30 mK, and the authors have studied its response to irradiation by 18 and 60 keV photons from an 241 Am source. This paper presents an analysis of the resolution of our detector, considering the noise of the front end electronics, and signals from extraneous sources such as microphonics.
