辐射场的计算最直接有效的方法是Monte-Carlo方法模拟,在已知束流损失的位置、角度和能量分布后,将这些信息作为Monte-Carlo软件的输入,即可模拟计算加速器及其周围的辐射场。适用于中高能质子输运的常用的Monte-Carlo方法软件有MCNPX、GEANT4、FLUKA和Mars等。FLUKA为CERN和INFN联合开发,在Linux下运行,有开源代码,残余射场的计算通过精确求解
The most direct and effective method of radiation field calculation is Monte-Carlo simulation. After knowing the location, angle and energy distribution of beam loss, this information can be used as the input of Monte-Carlo software to simulate the accelerator and its surroundings The radiation field. Commonly used Monte-Carlo method software for medium and high energy proton transport are MCNPX, GEANT4, FLUKA and Mars. FLUKA is a joint development of CERN and INFN, running under Linux, with open source code, the calculation of the residual field by accurate solution
