Abstract: The results of computer simulation of heat distribution processes taking place after absorption of single photons of 1 eV-1 keV energy in three-layer sensor of the thermoelectric detector are being analyzed. Different geometries of the sensor with tungsten absorber, thermoelectric layer of cerium hexaboride and tungsten heat sink are considered. It is shown that by changing the sizes of the sensor layers it is possible to obtain transducers for registration of photons within the given spectral range with required energy resolution and count rate. It is concluded that, as compared to the single layer sensor, the thee-layer sensor has a number of advantages and demonstrate characteristics that make possible to consider the thermoelectric detector as a real alternative to superconducting single photon detectors.

 

Keywords: Thermoelectric, Single-photon detector, Multi-layer sensor.
