快中子发生器屏蔽的Monte－Carlo估计

The Calculation of Shielding Field of Fast Neutron Generator with Monte-Carlo Method

本文介绍的是一个在微机上实现的计算快中子屏蔽的Ｍｏｎｔｅ－Ｃａｒｌｏ程序．采用历次飞行法对结果进行统计估计，对中子发生器周围的屏蔽作了简单模拟，结果表明采用的物理模型是正确的．该程序改进后也可用于多次散射的计算，或模拟其他中子源的屏蔽，故有一定的实用价值．

A computer code for calculation of shielding field of fast neutron generator has been developed.A method of all previous successive flights were adopted to estimate the experimental results, and the shielding field around the fast neutron generator has been analysised with the code. The results show that the physical model is suitabe.This code, while modifield properly, can also be used to analysis the multiscattering and shielding field around other fast neutron generator.
