gamma ray imaging spectrometer

Abstract

The invention provides a spectrometer for gamma ray imaging, which consists of a uniform redundant array encoding board, a detection module, a front-end signal processing module, an A/D module, a control module, a data interface module, a power supply module, and a lead shielding layer composition. In the lead shielding layer, the uniform redundant array coding board is placed at the front of the detection module; the detection module is connected to the front-end signal processing module through a cable; the A/D module is connected to the front-end signal processing module, and then connected to the control module through a double row of pins The control module is connected to the data interface module through the cable socket; the data interface module is output to the upper PC through Ethernet; the power module processes the input low-voltage DC power of the system and supplies it to each module respectively. The gamma-ray imaging energy spectrometer provided by the invention can be used for both gamma-ray imaging and gamma-ray energy spectrum measurement.

Description

technical field [0001] The invention belongs to the technical field of gamma-ray radiation measurement, and in particular relates to a gamma-ray imaging energy spectrometer. Background technique [0002] Gamma rays are produced by changes in the internal state of the nucleus, that is, the light emitted during the transition of the nucleus from an excited state to a lower energy level, so the gamma spectrum can reflect some of the characteristics of the nucleus; different elements emit different gamma rays , different elements can be distinguished by the characteristic spectrum of gamma rays emitted by radioactive element decay. Through the diagnosis of different gamma rays, the image and energy spectrum data of the gamma ray source can be obtained, and then the type and position of the gamma ray source can be obtained. Gamma-ray imaging and energy spectrum diagnosis are of great significance for physical experiments and radiation material inspection. [0003] The methods u...
