摘要：
We are developing a low temperature detector for dark matter based on single crystal superconducting Nb. This work requires a detailed knowledge of the behaviour of phonons and quasiparticles in Nb which arise from particle interactions. We discuss the use of superconducting tunnel junctions (STJs) and series connected arrays of superconducting tunnel junctions (SASTJs) to detect the high energy phonon flux arising from laser and particle interactions. The signal shapes and their variation with temperature for Al-Ox-Al and Sn-Ox-Sn junctions are discussed.
