Abstract
The mathematical modelling of the X-ray detectors based on superconducting tunnel junctions was performed taking into account diffusion of nonequilibrium quasiparticles, quasiparticle tunnelling and losses, self-recombination and exchange 2\(\Delta \)-phonons. The effects of recombination were examined in detail. The dependence of the signal on the photon energy and the energy resolution of the detectors were considered. A new analytical expression for a contribution of self-recombination to the signal was obtained.
