Scientific paper

The optimization of far infrared photoconductive detectors for use in balloon-borne or satellite-borne limb sounding atmospheric spectrometers was investigated. Instruments of this kind find important applications in the study of stratospheric chemistry, and the influence of anthropogenic pollutants. The choice of detector type for a given spectral region, and the optimization of the operational parameters (temperature, bias voltage, readout electronics) to achieve the best detector performance (detective quantum efficiency, speed of response) are considered. Results are presented for Ge:Ga, Ge:Sb, Ge:Be, Ge:Zn, bulk photoconductors, and for Si:Sb BIB detectors.
