AI总结:

本文将导电介质扩展的 Ramo-Shockley 定理应用于 1 MΩ/□ 二维电阻条体 MicroMegas,利用 80 GeV/c μ子径迹和有限元法计算信号扩散,并通过测试束测量为电阻粒子探测器信号感应的微观建模方法提供基准测试。

摘要:

正如 ATLAS New Small Wheel 社区通过其 MicroMegas (MM) 设计所证明的那样,电阻电极目前已被应用于 Micro Pattern Gaseous Detector 家族的不同探测器类型中,以提升其鲁棒性或性能。导电介质的 Ramo-Shockley 定理扩展形式已被应用于一个 1 MΩ/□ 的二维电阻条体 MM 上,利用 80 GeV/c 的μ子径迹来计算信号向相邻通道的扩散。针对此几何结构,通过应用结条件和坐标缩放技术,以准确表示 10×10 cm² 有效面积的边界条件,使用有限元求解器数值求解了动态权重势。利用测试束测量结果,该模型的结果将用于对电阻粒子探测器中信号感应的微观建模方法进行基准测试。

英文摘要:

As demonstrated by the ATLAS New Small Wheel community with their MicroMegas (MM) design, resistive electrodes are now used in different detector types within the Micro Pattern Gaseous Detector family to improve their robustness or performance. The extended form of the Ramo-Shockley theorem for conductive media has been applied to a 1 M$Ω$/$\Box$ 2D resistive strip bulk MM to calculate the signal's spreading over neighbouring channels using an 80 GeV/c muon track. For this geometry, the dynamic weighting potential was obtained numerically using a finite element solver by applying a junction condition and coordinate scaling technique to accurately represent the boundary conditions of a $10\times 10$ cm$^2$ active area. Using test beam measurements, the results of this model will be used to benchmark this microscopic modelling methodology for signal induction in resistive particle detectors.
