Description

The ALPHA experiment situated within CERN Antiproton Decelerator (AD) produces, captures and studies atoms of antihydrogen and compares these with hydrogen atoms. Creating antihydrogen depends on bringing together the two component antiparticles, antiprotons and positrons, in a trapping device for charged particles. The ALPHA apparatus has recently been proposed to be upgraded by detection of 511 keV photons by semiconductor sensors. One possibility for direct high energy photon detection is Cadmium Telluride (CdTe) based sensors. CdTe is evolving detection technology for e.g. nuclear safety and medical imaging applications. Moreover, CdTe sensors can be used in single photon counting mode with very high readout rate if attached into CMOS ASIC chips developed for particle physics applications. High readout rate together with precise spatial resolution potentially unfolds new possibilities for experimental antimatter physics. The focus of this workshop is to bring together expertise from Helsinki Institute of Physics (HIP), University of Helsinki, University of Liverpool, University of Swansea and Ruder Boskovic Insitute (RBI) to discuss and survey common interests for high energy photon detection by CdTe sensors.
