Description
Ring Imaging Cherenkov detectors are moving towards new photodetection technologies for exploring more accurate timing and amplitude resolutions. Silicon photomultipliers (SiPMS) can play such a role, played by photomultiplier tubes until now. SiPMs measure single photon signals with time resolutions up to picoseconds. Their photodetection efficiency surpasses the photomultiplier tubes, reaching up to 50% (in Near Ultra-Violet SiPMs, 60%). The SiPM's fill factor was a problem in the early times of SiPMs, but it has enhanced to 90% nowadays. The main SiPM drawbacks are temperature dependency and high dark count rates. We are investigating methodologies for temperature effect compensation in SiPMs and new trigger systems for readout electronics.
