As part of the development program for the Dutch experiment in the infrared astronomy satellite (IRAS), the performance of arsenic doped silicon photoconductive detectors, associated pre-amplifiers and spike-suppression circuitry has been evaluated. These detectors are part of the spectrometer in IRAS which will operate between 6.5 and 24 microns. Measurements of detector responsivity and system noise as a function of frequency, temperature, bias, etc., show that at 12.5 microns NEP = 10 to the -16th W/Hz to the 1/2 should be achieved. The results of an inhouse detector and preamplifier test program are summarized, and the test set up used for the performance evaluation is described.
