DEVELOPMENT OF VIRTUAL SIMULATION EXPERIMENT FOR GAMMA RAY

For the limitation of some nuclear physics experiments, a virtual simulation experiment system of “gamma ray comprehensive experiment” is developed. Based on GEANT4 and Unity3D, the system restores and expands the experimental contents of measurement of gamma ray spectrum, measurement of gamma absorption coefficient and measurement of Compton scattering in the original syllabus, and introduces a defects inspection by Compton gamma-rays backscattering, which meets the multi-level needs from the basic theoretical knowledge of ordinary undergraduates to the scientific exploration and scientific research training of professional postgraduates. This paper briefly introduces the experimental modules are briefly introduced, with a detailed introduction to the defects inspection by Compton effect module, and finally summarizes the effect of this experiment in multi-level teaching.
