SiPMt
SiPMt, or Silicon Photomultiplier Tube, is a type of photodetector used in various scientific and industrial applications. It is a solid-state device that converts light into electrical signals, offering several advantages over traditional photomultiplier tubes (PMTs). SiPMt devices are typically composed of a large number of avalanche photodiodes (APDs) connected in parallel. When a photon is absorbed by the silicon substrate, it generates an electron-hole pair. The electric field in the depletion region of the APD accelerates these carriers, leading to an avalanche multiplication process. This results in a significant increase in the number of charge carriers, which is then collected and converted into an electrical signal.
One of the key features of SiPMt is its high gain, which allows for the detection of
However, SiPMt devices also have some limitations. They typically have a higher dark count rate compared to
