More-over, there can be one or more interactions of a gamma and there may be multiple gam-mas emitted from a single nuclear decay. Usu-ally, all energy depositions in the scintillator from a single decay are effectively simultane-

The secondary electrons are detected by a scintillator-photomultiplier combination which is known as the Everhart-Thornley detector. Its construction is shown in Fig. 1.1.2b which is taken form [1.1.2]. The secondary electrons are collected by a grid.
X-ray detectors - Hamamatsu
www.hamamatsu.comScintillator detectors are widely used in these applications. These detectors use scintillators to convert X-rays into light and detect this light to detect X-rays indirectly. Especially in the medical field, the digital X-ray method, which uses X-ray detectors with large photosensitive area, is becoming mainstream, replacing the

The reason for this conversion of an electrical signal to an optical signal and back to an electrical signal is to electrically isolate the flight tube and the front of the detec-tor, which are at roughly –6,500 volts, from the PMT, whose signal output is at
