论文摘要
电阻板室（RPC）是一个气态检测器，以其良好的空间分辨率和出色的时间分辨率而闻名。由于其快速响应和出色的时间分辨率，因此用于触发和时机目的。但是RPC的时间分辨率取决于检测器几何形状，施加的电压和用于检测器操作的气体混合物。在这项工作中，我们试图开发一个数值模型来估计检测器的时间分辨率。该模型是使用Comsol Multiphysics开发的，这是一种可商购的有限元方法求解器。该模型使用来自Heed的主要电离信息和Magboltz的电子传输性能，求解了玻尔兹曼方程，以模拟检测器中的雪崩，并找到时间越过先前确定的阈值电流，该电流用于测量检测器的时间分辨率。
Resistive Plate Chamber (RPC) is a gaseous detector, known for its good spatial resolution and excellent time resolution. Due to its fast response and excellent time resolution, it is used for both triggering and timing purpose. But the time resolution of RPC is dependent on the detector geometry, applied voltage and the gas mixture used for detector operation. In this work, we have tried to develop a numerical model to estimate the time resolution of the detector. The model is developed using COMSOL Multiphysics, a commercially available finite element method solver. Using the primary ionization information from HEED and the electron transport properties from MAGBOLTZ, the model solves the Boltzmann equations to simulate the avalanche in the detector and finds the time to cross a previously determined threshold current, which is used to measure the time resolution of the detector.
