论文摘要
对多层10B-RPC热中子检测器进行了基于蒙特卡洛模拟的优化，以靶向增加计数率能力的增加，同时维持热中子的高（> 50％）检测效率。各个RPC的转换器层厚度已针对包含10个双GAP RPC的堆栈的几种检测器的多种配置进行了优化。结果表明，与只有一个双间隙RPC的检测器速率相比，可以达到计数率，该计数率高出八倍。分析了探测器内中子散射的作用，并提出了第一个检测器原型（在中子束测试）的设计修饰。
A Monte Carlo simulation-based optimization of a multilayer 10B-RPC thermal neutron detector is performed targeting an increase in the counting rate capability while maintaining high (>50%) detection efficiency for thermal neutrons. The converter layer thicknesses of individual RPCs are optimized for several configurations of a detector containing a stack of 10 double gap RPCs. The results suggest that it is possible to reach a counting rate which is by a factor of eight higher in comparison to the rate of a detector with only one double-gap RPC. The effect of neutron scattering inside the detector contributing to the background is analyzed and design modifications of the first detector prototype, tested at neutron beam, are suggested.
