论文摘要
在II期Atlas升级中引入了具有1 mm间隙尺寸的薄间隙电阻板腔室（RPC）。较小的雪崩电荷由于差距的减少而引起了信号完整性的担忧。这项工作着重于无损条件下的RPC信号传播过程，并为Atlas RPC实施了分析研究。提出了检测器建模，并详细讨论了RPC信号的仿真。将模拟的特征阻抗和串扰与测量值进行了比较，以验证该模型。此方法应用于不同的RPC设计几何形状，包括新提出的$η-η$读取方案。
Thin-gap Resistive Plate Chambers (RPCs) with a 1 mm gap size are introduced in the Phase-II ATLAS upgrade. Smaller avalanche charge due to the reduced gap size raises concerns for signal integrity. This work focuses on the RPC signal propagation process in lossless conditions, and an analytical study is implemented for the ATLAS RPC. Detector modeling is presented, and the simulation of the RPC signal is discussed in detail. Simulated characteristic impedance and crosstalk have been compared with the measured value to validate this model. This method is applied to different RPC design geometries, including the newly proposed $η-η$ readout scheme.
