本文简单介绍了蒙特卡罗方法及MCNP程序,利用MCNP程序,计算出了射线束从不同方向入射时电离室的能量响应特性,模拟计算结果与试验结果符合得很好。
In this paper, the Monte Carlo method and the MCNP program are briefly introduced. The MCNP program is used to calculate the energy response of the ionization chamber when the beam is incident from different directions. The simulation results are in good agreement with the experimental results.
