“…Temperatures of 50 o to 100 o C and durations of days to weeks are typical of operations in space [41; 15]; when in doubt, the longer and warmer, the better [16]. Some annealing does take place at room temperature [53] but takes longer to be effective, and cannot eliminate trapping completely.…”

The detection of photons above 10 keV through MeV and GeV energies is challenging due to the penetrating nature of the radiation, which can require large detector volumes, resulting in correspondingly high background. In this energy range, most detectors in space are either scintillators or solid-state detectors. The choice of detector technology depends on the energy range of interest, expected levels of signal and background, required energy and spatial resolution, particle environment on orbit, and other factors. This section covers the materials and configurations commonly used from 10 keV to >1 GeV.

Spectrometric characteristics of High Pressure Xenon (HPXe) gamma-ray spectrometer "Ksenia" was studied during operation of this instrument onboard the orbital station "MIR". The energy resolution of this spectrometer is 3.5*0.5% at Ey = 511 keV and stable during period from May1990 till May 1997. The position of 511 keV gamma line is also stable (k1 channel or +4keV). The total number of trapped in Radiation Belt particles passed through the detector is 5~1 0~. Neutrons of atmospheric albino is 2.10''.No activated gamma-lines were found during the flight.After intensive activation (fluence about 1.5.10'' neutrons) of cylindrical HPXe spectrometer with volume of Xe about 6 litters at the laboratory few activated gamma-lines were registrated: Ey=164 keV, TIl2=11.92 from 131Xem; Ey=236 keV, T112=8.89 days from 129Xem and Ey=847 keV, TIl2=2.56 hours from 56Mn.The intensity of these lines is not large so it is possible to operate HPXe spectrometers even after intensive irradiation.
