Paper Abstract

The electron and phonon energy distributions arising in small-size metal absorbers of microwave radiation detectors operating at ultralow temperatures have been calculated using the kinetic equation. It is shown that the electron and phonon distributions are nonequilibrium, significantly different from the Fermi and Bose distributions. The form of electronic and phonon nonequilibrium distributions are determined by the ratio of the rates of electron-electron and electron-phonon relaxation and by the ratio of non-equilibrium phonons escape rate from the absorber and a velocity of a phonon - electron relaxation. The influence of the measuring element (superconductor-insulator-normal metal junction) on the absorber is also take into account. The response of such a bolometer is calculated and compared to the experimental data. The recommendations for magnification of the bolometer response in experiment are suggested.
