摘要
利用GEANT4蒙特卡罗软件程序包,建立了10 MeV工业辐照电子加速器数学模型,并模拟计算了不同密度下均质产品剂量分布数据。结合Qt界面设计开发平台,对模拟数据进行C++编程计算,获得了各种产品密度、不同厚度单双面辐照剂量分布图及辐照不均匀度等参数。同时,利用Qt将产品辐照剂量与束下装置传送速度计算、日常工艺管理和剂量场分布数据绘图等功能界面化,研制了辐照工艺界面软件。经过产品剂量分布测试实验和对行业研究结果比较,验证了GEANT4模拟计算结果和工艺软件准确性。实验表明:计算和测试结果具有很好的吻合性。辐照工艺界面软件可以快速显示产品辐照效果及计算传送速度等主要工艺参数,为产品辐照工艺设计提供了有力工具。
A mathematical model of a 10 MeV industrial electron accelerator was established by using GEANT4 Monte Carlo software package, and the dose distribution of homogeneous products under different densities were obtained by simulation calculation. Combined with the Qt interface design and development platform,the calculated data were designed by C++ programming. The dose distribution and dose uniformity ratio of different product densities and thicknesses were obtained. In addition, Qt was used to interface the product irradiation dose and the conveyor device transmission speed calculation, daily process management, and dose field distribution data drawing, forming the irradiation process interface software. The accuracy of GEANT4 simulation calculation results and process software was verified by using dose distribution tests and industry research results. The experimental results revealed that the calculation results and test results are in good agreement. The irradiation technology interface software, which can be applied to calculate the irradiation effect and transmission speed of products and other main process parameters in real time, is a useful tool for product irradiation technology design.
