Photomultiplier tubes (PMTs) are one of the first devices developed that can detect … Webb17 mars 2024 · Photomultiplier tube. A photomultiplier tube is a vacuum electronic device that converts a weak optical signal into an electrical signal. Photomultiplier tubes are used in optical measuring instruments and spectroscopic instruments. It measures very weak radiated power from 200 to 1200 nm in low-energy photometry and spectroscopy.

One of the paths was focused on the optical power measurement device, another path was focused on the photomultiplier tube (PMT, Hamamatsu H10682-210), and a high-resolution oscilloscope (OS) captured the output signal from PMT. WebbBoth crystals are optically coupled to a single photomultiplier tube. A real-time, FPGA-based digital pulse shape analysis was developed to discriminate and reject Compton-induced pulses from the CsI(Tl) crystal. All the digital pulse processing functions including pulse shape discrimination analysis, ...

The gated photomultiplier tube circuit add-on is an excellent option for the measurement of samples which contain emission occurring on different timescales. By time-gating, the PMT-900 or PMT-980 detectors of the FLS1000, the fluorescence emission can be removed allowing phosphorescence decays to be acquired more rapidly. In ...
