摘　　要：质子在医学、材料科学、辐射成像等领域有着广阔的应用前景,质子输运过程的数值模拟是质子应用理论分析的重要手段。本研究基于Geant4软件编写了蒙卡模拟程序,研究了程序的加速方法。结果表明,次级粒子截断和并行计算可以有效加快程序的运行速度。程序易于扩展,为质子应用的快速模拟奠定了基础。Proton has bright future in the field of medical, material analysis and radiography. Numerical simulation provides a good way to analyze the process protons transmitting through materials. This article establishes a Monte Carlo program based on Geant4. The accelerating method is introduced. The result implies that secondary particles cut and program paralleled can shorten the time cost effectively. The program can be easily extended which provides a good foundation for fast simulation of proton transportation.
