Abstract

The ALPS II experiment, Any Light Particle Search II at DESY in Hamburg, will look for light (m 10-4 eV) new fundamental bosons (e.g., axion-like particles, hidden photons and other WISPs) in the next years by the mean of a light-shining-Through-The-wall setup. The ALPS II photosensor is a Transition-Edge Sensor (TES) optimized for = 1064nm photons. The detector is routinely operated at 80 mK, allowing single infrared photon detections as well as non-dispersive spectroscopy with very low background rates. The demonstrated quantum efficiency for such TES is up to 95% at = 1064nm as shown in [1]. For 1064 nm photons, the measured background rate is 10-2 sec-1 and the intrinsic dark count rate in a dark environment was found to be of 1.0 10-4 sec-1 [2]. Latest characterization results are discussed.
