An RPM is a large pass-through radiation monitor (or "portal") for personnel, vehicles, container boxes, or trains. SiPms can be operated up to 60 degrees C. For applications where small size and low voltage operations are required, SiPm readout of scintillators can be a good choice. Usually, this voltage is prescribed by the PMT manufacturer. (from Knoll) The scintillation mechanism is different for these two types. A sensitive photodetector (usually a photomultiplier tube (PMT), a charge-coupled device (CCD) camera, or a photodiode) converts the light to an electrical signal, and electronics process this signal. This trend is due to their more compact structure, lower supply voltage, and robustness to magnetic fields. However, because of their stratification, the reflectivity of the DBR turns out to be highly angular dependent. U.S. Department of Energy, Nuclear Physics and Reactor Theory. Glasstone, Sesonske. A standard resistor value between dynodes is 470kW. A quite substantial improvement in the performance of BGO has indeed been obtained, whereas its use on LYSO crystals showed a milder gain.
