Test Facilities Overview

In the context of SENSE a collaboration between several labs experienced in measuring photosensors was developed and is regulated within a MoU. The aim is to characterize LLL sensors and standardize measurements and analysis procedures. Each lab has slightly different test facilities for the measurement of photosensors so as a first step each platform is characterized and systematic errors relevant for various measurements are compared. By this, doubled efforts characterizing sensors are minimized and common precisions on measured quantities are established. All results should be published jointly under open access.

A Cooperation Agreement for providing a framework for the testing and performance studies of photosensors was developed and all included test facilities will be described in detail below. At the moment the document is signed by the following institutions:

Universitiy of Geneva, Départment de Physique Nucleaire et Corpusculaire (UNIGE)
Max-Planck-Institut für Physik (MPI)
KIT-Centrum Elementarteilchen und Astroteilchenphysik (KIT)
Deutsches Elektron Synchrotron (DESY)
Institute for Space-Earth Environmental Research, Nagoya University (Nagoya)
INAF-Osservatorio Astrofisico di Catania (INAF-CT)
University of Heidelberg, Kirchhoff-Institut für Physik
