论文摘要
使用10b层作为中子转换器的基于气体电子乘数（GEM）的检测器变得流行在热中子检测中。模拟这种检测器的一种常见策略是基于两个框架：Geant4和Garfield ++。第一个提供了中子和10b层之间核相互作用的模拟，而第二个则允许模拟反应产物与检测器气体的相互作用，从而导致气体分子的电离和激发。考虑到这些核反应产物的高电离能力，完整的模拟非常耗时，必须优化才能变得可行。在这项工作中，我们提出了一种基于这两个框架来开发快速模拟器的策略，该框架将使我们能够生成足够的数据，以正确评估这种检测器的预期性能和优化。我们将通过此工具专注于其验证和性能获得的第一个结果。
Gas Electron Multiplier (GEM)-based detectors using a layer of 10B as a neutron converter is becoming popular for thermal neutron detection. A common strategy to simulate this kind of detector is based on two frameworks: Geant4 and Garfield++. The first one provides the simulation of the nuclear interaction between neutrons and the 10B layer, while the second allows the simulation of the interaction of the reaction products with the detector gas leading to the ionization and excitation of the gas molecules. Given the high ionizing power of these nuclear reaction products, a full simulation is very time consuming and must be optimized to become viable. In this work, we present a strategy to develop a fast simulator based on these two frameworks that will allow us to generate enough data for a proper evaluation of the expected performance and optimization of this kind of detector. We will show the first results obtained with this tool concentrating on its validation and performance.
