Splet12. apr. 2024 · Current commercial photon counting detectors based on SiPMs have several limitations, including their cost, size and temperature sensitivity. Since our detector is not as sensitive to temperature or as susceptible to magnetic fields, it can be used for a broader range of scientific and everyday applications than current photon detectors. SpletWith a high-efficiency GaAsP cathode a hybrid photomultiplier reaches the efficiency of a single-photon avalanche photodiode (SPAD), but with a cathode area several orders of magnitude larger. The perhaps most significant advantage of the hybrid detector has only been recognised recently: The hybrid PMT is virtually free of afterpulsing.
