Abstract

The invention discloses a gamma ray detector and a gamma ray processing method. The gamma ray detector comprises n scintillation crystals with the numbers from A1 to An, a first photoelectric converter, a second photoelectric converter and a processing circuit. The n scintillation crystals are arranged side by side, a scintillation crystal Ai and a scintillation crystal Ai+1 are arranged in an end-to-end mode; the first photoelectric converter is arranged at the first end of a scintillation crystal A1; the second photoelectric converter is arranged at the first end of a scintillation crystal An; the processing circuit is connected with the first photoelectric converter and the second photoelectric converter and is used for receiving a first pulse and a second pulse, and the incidence position of gamma rays is computed and / or the energy of the gamma rays is corrected according to the first pulse and the second pulse. According to the gamma ray detector and the gamma ray processing method, the problem that in the existing gamma ray detecting technology, the axial resolution ratio is low, and gamma ray energy detecting accuracy is low is solved, and accordingly the purpose that the measuring accuracy of the gamma ray detector is improved is achieved.

Description

technical field [0001] The present invention relates to the technical field of detection, in particular to a gamma ray detector and a gamma ray processing method. Background technique [0002] In the field of geological exploration, different formations have different contents and types of radioactive elements. Using a gamma ray detector to detect the intensity of gamma rays in the formation can distinguish the formation and determine the elements of the formation. figure 1 is a structural schematic diagram of a gamma-ray detector commonly used in the prior art, such as figure 1 As shown, the current gamma ray detector generally consists of a scintillation crystal A and a photomultiplier tube R arranged at one end of the scintillation crystal A. When a gamma ray is injected into the scintillation crystal, scintillation light will be generated, which is generated by photomultiplier The tube collects photoelectrons, multiplies and generates pulse current at the output end, f...
