Abstract: Aiming at the disadvantages of traditional γ-ray detection experimental equipment such as low positioning accuracy, troublesome construction, few experimental projects that can be carried out, and not conducive to experiment repetition and teaching, this paper designs and develops a comprehensive experimental teaching platform for the γ-ray detection and measurement, completes the mechanical design and processing of the platform, and develops a multifunctional digital energy spectrometer for the γ-ray detection. Based on this platform, several cognitive, basic, comprehensive, and exploratory experimental projects on γ-ray detection and application can be completed. Practical teaching results have proved that the platform has good stabilitytt, strong operability, and accurate experimental results, and it is convenient for teachers to teach, which can enable students to better understand and master the properties of γ-rays, the mechanism of γ-rays interacting with substances, and the applications of γ-rays.
