Time response, linearity, and gain of 250-micron silicon solid-state detectors

Experiments are described in which the time response, linearity, and gain were determined for the 250-micron silicon solid-state detectors used in a solid-state magnetic gamma-ray spectrometer. Time-response measurements performed at the EG and G/AEC linear accelerator (linac) determined detector impulse response, step response, frequency-domain amplitude, and phase as a function of frequency. Linearity measurements performed with the linac determined detector current and charge linearity at bias levels up to 500 V. Gain measurements made in the counting mode at the NBS Dynamitron (0.25 to 1.0 MeV) and Van de Graaff (2.0 to 4.0 MeV) accelerators determined gain as a function of incident electron energy. (U.S.)
