WebbThe photomultiplier tube is one of the most sensitive light detectors, and is still widely used in physics research. Operating principles [ edit ] Phototubes operate according to … WebbConclusion. 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 ...
