The Static Simulation Of Gamma Shutdown Sensor

This work is the application of the Monte Carlo method to simulate the relationship between the count rate of sensor and height.The aim is to achieve a high degree of real-time monitoring and issue shutdown signal at a specified height.This work is supported by the comparison of the simulation and ground tests.We want to verify the reliability and accuracy of the simulation program and lay the foundation for the gradual transition to the lunar surface environment.Provide accurate and reliable theoretical guidance to design a stable shutdown sensor working in the environment of the lunar surface.
