北京谱仪BESIII主漂移室(MDC)设计性能的提高要求更为精确的探测器模拟。文章主要介绍MDC的模拟,并对模拟中斜丝层几何构造和丝物质处理的方法进行了详细的描述。通过大量蒙特卡罗样本的产生和分析,表明模拟是合理的。
Beijing Spectrometer BESIII main drift chamber (MDC) design performance improvements require more accurate probe simulation. The paper mainly introduces the simulation of MDC, and describes the method of the geometry and the material handling of the inclined layer in the simulation. The production and analysis of a large number of Monte Carlo samples show that the simulation is reasonable.
