Abstract

Physical aspects of a novel read-out method for low-temperature direct detectors are analysed. The method uses relaxation oscillations in asymmetric S1IS2 junctions biased in the 'voltage-source' regime (S1.2 are superconductors and I is an insulator). Using a model Sn-I-Pb junction, it is shown that perturbations caused in the superconducting electrode with lower critical temperature under the influence of absorbed high-energy particles may be detected by measurement of the frequency of relaxation oscillations which take place in the system. The change in the frequency is proportional to the energy of the particles.
