Description
Modern experiments in hadronic physics require detector systems capable of identifying and reconstructing all final-state particles and their momentum vectors. The PANDA experiment at FAIR and the CLAS12 experiment at Jefferson Laboratory both plan to use imaging Cherenkov counters for particle identification. CLAS 12 will feature a Ring Imaging Cherenkov counter (RICH), while PANDA plans to construct Cherenkov counter relying on the Detection of Internally Reflected Cherenkov light (DIRC).
These detectors require high-rate, single-photon capable light detection system with sufficient granularity and position resolution. Several candidate systems are available, ranging from multi-anode photomultiplier tubes to micro-channel plate systems to silicon photomultipliers. Each of these detection solutions has particular advantages and disadvantages.
We present detailed studies of rate dependence, cross-talk, time-resolution and position resolution for a range of available photon detection solutions: Hamamatsu MAPMTs, MCP-PMTs from Photonis and Hamamatsu and a variety of SiPMs. We will conclude on their applicability to the PANDA and CLAS12 Cherenkov counters.
