Best photomultiplier tubes. Feb 1, 2023 · Photomultiplier tubes Most PET detectors produced up to now have been based on photomultiplier tubes (PMTs). Photomultiplier tubes (PMTs) are commercially available from 120 to 1200 nm (albeit not in one device) and have: • a fast rise time (1–2 ns side window, 10–15 ns end window); • excellent current amplification; • a wide linear dynamic range (typically 10 6 or better); and • a low dark current (typically 0. Someone mentioned Photomultiplier tubes the other day so here’s a picture of one use with a scintillator in a Geiger-counter. While a PMT was the first device to detect light at the single-photon level, invented more than 80 years ago, they are widely used to this day, particularly in biological and medical applications. A PMT is a vacuum glass tube that contains a photocathode, a series of electrodes with increasing voltage called dynodes, and an anode. APDs are widely used in instrumentation and aerospace applications, offering a combination of high speed and high sensitivity unmatched by PIN detectors, and quantum efficiencies This handbook will help the user gain maximum performance from photomultiplier tubes and show how to properly operate them with higher reliability and stability. Introduction For low-light detection in the 200 to 1150 nm range, the designer has three basic detector choices - the silicon PIN detector, the silicon avalanche photodiode (APD) and the photomultiplier tube (PMT). These detectors multiply the current produced by incident light by as much as 100 million times or 10 8 (i Feb 25, 2026 · There are many types of photomultiplier tubes with different characteristics in shape, spectral response range, structure, and effective area, etc. Watch short videos about photomultiplier tube uses from people around the world.
