Abstract
An all-sky monitor (MVN) is an instrument intended for a long-term experiment for measurement of cosmic x-ray background (CXB). It will be installed on the international space station (ISS) surface in 2018. In this instrument four CdTe detectors are used to measure CXB energy spectrum. To obtain accurate spectral measurements with planned accuracy, detectors’ temperature should not deviate by more than two degrees from minus 30◦C during the experiment. Thermal stabilization of the detectors is complicated because of strongly variable external thermal conditions on the ISS surface. Influence of variable heat fluxes can be compensated for by using oppositely oriented radiators. In this article we describe the method application in the case of MVN.
