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.

An ageing study of resistive micromegas for the HL-LHC environment
电阻阳极微兆气体探测器已经开发了几年,以解决在高通量和高电离辐射下工作时的火花问题,如在HL-LHC中(高达LHC亮度的十倍)。它们已被选为ATLAS新小轮项目(前向μ子系统)的技术之一。老化研究是强制性的,以评估它们长期处理HL-LHC环境的能力。一个原型已经暴露于几种类型的辐射(X射线,冷中子,$^{60}$ Co γ和α)以上的等效电荷在五个HL-LHC运行年的探测器在增益和能量分辨率方面的性能没有显示出任何退化。这项研究已经完成了跟踪性能的表征效率和空间分辨率方面,验证了与电阻micromegas探测器,辐照和非辐照的一个获得的结果的兼容性。

本文介绍了一种新颖的光敏气体探测器,它由双层电极(而不是通常使用的金属电极)涂有CsI反射光电阴极的GEM放大结构组成。在我们的最新设计中,内部电极由金属网格组成,外部电极由电阻条组成;后者通过丝网印刷技术在金属条网格顶部制造。内部金属网格用于2D位置测量,而电阻层在高增益下提供有效的火花保护操作-接近击穿极限。探测器的有效面积为10 cm × 10 cm和10 cm × 20 cm,在各种条件下进行了测试,包括在含有乙基二茂铁或TMAE蒸汽的光敏气体混合物中的操作。新技术可以有许多应用需要强大和可靠的大面积紫外可视化检测器,例如,在切伦科夫成像设备。
