High sensitivity Si:P and Ge:Li photoconductive i.r. detectors for low photon background applications
No full textExtrinsic photoconductor detectors for the wavelength range 2 microns to 240 microns
No full textExtrinsic photoconductors are favored detectors for infrared photon detection in astronomical instruments of cooled space telescopes which provide low background flux conditions. Elementary silicon and germanium host crystal detectors doped by shallow impurities cover the infrared spectral range from 2 to 120 micrometers, and up to 240 micrometers by application of high uniaxial stress to germanium. The instruments of ISO (Infrared Space Observatory) are equipped with extrinsic photoconductors. The physical background and the status of the detector technology of the ISO detectors is described. The designs and the mounts are given. The measurement method of the spectral response used is presented
