Abstract

The invention provides a detector and a detection system, wherein the detector includes a plurality of unit crystals arranged in a matrix, and each unit crystal generates visible light after absorbing gamma rays; a position-sensitive photomultiplier tube coupled with the crystal array is used to It is used to convert the visible light received on each area corresponding to each unit crystal into an electrical signal, and the electrical signal is used by the data processing device to count the number of gamma ray absorption cases distributed on each unit crystal and to measure the amplitude of the electrical signal Analyze and realize the energy spectrum measurement of gamma rays. Only one position-sensitive photomultiplier tube is needed, and the structure is simple and the detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detector and a detection system. Background technique [0002] Radiation detection can be widely used in various radioactive environments, such as laboratories, nuclear power plants, nuclear fuel plants, large heavy ion accelerators, radioactive source libraries, etc. The existing detectors are various, and some detectors can locate the radioactive source, but most of them have the following problems: they are composed of crystals that are not easy to process, multiple different photomultiplier tubes and collimators, and the structure is complex, The detection efficiency is low and the operation is time-consuming. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a detector and a detection system with simple structure and high detection efficiency. [0004] A detector comprising [0005] A crystal array, including a p...
