Acquisition of quasi monoenergetic gamma rays by MC simulation of cobalt source scattering

This paper introduces a kind of access to ray based on Compton scattering experiment method, and simulated the whole process of obtaining quasi mono-energetic gamma ray by using Monte Carlo method, to determine the impact range of the related parameters and the optimum values, greatly improves the signal-to-noise ratio, scattering ray intensity, detection efficiency, scattering efficiency the system. The reliability of the simulation and the practicability of the method are verified by comparison with the experimental results. (authors)
