Multi-line gamma-ray spectrometer performance of a Si(Li) detector stack

Experimental data is presented which for the first time displays multi-line spectrometer performance of a Si(Li) detector stack at elevated temperature. The stack consists of four elements, each with a 2 cm diameter active area. /sup 133/Ba and /sup 110m/Ag spectra are obtained using various techniques to enhance the peak-to-background ratio. Spectral data are shown as a function of temperature (94 K/spl les/T/spl les/230 K) using optimized peak shaping.<
