KLauS is an ASIC produced in the AMS 0.35µm SiGe technology to read out the charge signals from silicon photomultipliers. Developed as an analog front end for future calorimeters with high granularity as pursued by the AHCAL concept in the CALICE collaboration, the ASIC is supposed to measure the charge signal of the sensors in a large dynamic range and with a high precision. In order to compensate...
This paper describes an experimental setup that has been developed to measure and characterise properties of silicon photomultipliers (SiPM). The measured SiPM properties are of general interest for a multitude of potential applications and comprise the photon detection efficiency (PDE), the voltage dependent cross-talk and the after-pulse probabilities. With the described setup the absolute PDE can...
