Abstract

The invention belongs to the technical field of radioactive detection equipment, particularly relates to a plastic scintillator detector device, and provides the following scheme aiming at the problems that a plastic scintillator detector in the current market is poor in installation stability, easy to loosen, tedious in disassembly operation and inconvenient to maintain: the plastic scintillator detector device comprises a detector shell, a bottom cover and a plastic scintillator, a stepped hole is formed in the inner wall of the top of the detector shell, the plastic scintillator is arranged in the stepped hole, a photomultiplier is arranged in the detector shell, the bottom cover is movably connected to the outer side of the detector shell in a sleeving mode, a tube base and a front circuit board are arranged in the bottom cover, the bottom of the front circuit board abuts against the inner wall of the bottom of the bottom cover, and the bottom of the front circuit board abuts against the inner wall of the bottom of the bottom cover. The top of the front circuit board abuts against the bottom of the tube socket. The plastic scintillator detector bottom cover is mounted through cooperation of the bent plate and the clamping groove and cooperation of the square plate and the positioning groove, the mounting stability is guaranteed, and dismounting work is facilitated.

Description

technical field [0001] The invention relates to the technical field of radiation detection equipment, in particular to a plastic scintillator detector device. Background technique [0002] Plastic scintillator detectors are commonly used detectors in the field of radiation measurement. The plastic scintillator detectors used for radiation detection in the domestic market are mainly radiation detectors composed of plastic scintillators, photomultiplier tubes and front plates. The principle is that when the rays enter the plastic scintillator, the atoms or molecules of the scintillator are excited to generate fluorescence, and the photomultiplier tube amplifies the generated fluorescence and converts it into an electrical signal, which is sent to the front panel for processing. [0003] At present, the installation stability of plastic scintillator detectors on the market is not good, it is easy to loosen, and the disassembly operation is cumbersome, resulting in inconvenient ...
