Description
The ALPS (Any Light Particle Search) experiment, located at DESY, goes in its second phase. To increase the sensitivity the experiment will be bigger and fancier: more laser power, a regeneration cavity and longer cavities. Besides of that improvements the collaboration is also looking for a new, more sensitive detector.
Because of the intrinsic noise of the CCD -- the present detector of ALPS -- now studies have started to build up an cryogenic single infrared photon detector. For that we use a Transition-Edge Sensor (TES), which is working at a superconducting transition in a Milli Kelvin range.
In this talk the principle of such a detector is explained and the application to ALPS and an overview of the recent work is given.
