Scientific paper

The energy resolution of a conventional silicon spectrometer is limited by the noise associated with leakage currents and capacitance. The noise can be reduced by cooling and by using detectors which have a small capacitance. In principle, silicon devices using drift technology should in some respects be superior to CCD's (Charge Coupled Devices). Measurements were made on both position sensitive spectrometers and large area photodiodes at low temperatures. Timing resolutions of a few microseconds, position resolutions of the order a fraction of a millimeter, and FWHM energy resolutions of 1 keV at 20 keV were obtained for single photon events in a 1 sq cm detector. As scintillator readout devices the photodiodes give a resolution comparable with that of conventional diodes when coupled to CsI(Tl) at room temperature, and superior to that of conventional diodes when coupled to BGO at low temperature.
