TY - CONF AU - Dreyling-Eschweiler, Jan TI - First sensitivity limits of the ALPS TES detector IS - DESY-PROC-2014-03 M1 - PUBDB-2014-03673 M1 - DESY-PROC-2014-03 PY - 2014 AB - The Any Light Particle Search II (ALPS II) requires a sensitive detection of 1064 nm photons. Thus, a low dark count rate (DC) and a high detection efficiency (DE) is needed. ALPS has set up a transition-edge sensor (TES) detector system, namely the ALPS TES detector. It is found that thermal photons from room temperature surfaces are the main contribution of dark counts for 1064 nm photon signals. Furthermore, the current setup of the ALPS TES detector shows an improvement compared to using the ALPS I detector.
