摘要:

目前,CERN LHC CMS探测器的前向RPC μ子系统的一部分在高η区仍然没有仪器。一项国际合作正在研究覆盖1.6 <|η| < 2.4区域的μ子端盖与大面积的三重GEM探测器。鉴于其良好的空间分辨率,高速率能力和辐射硬度,这些微图案气体探测器是一个有吸引力的选择,同时提高μ子跟踪和触发能力,在未来升级的CMS探测器。将对这一可行性研究进行概述。将描述小型(10个\times 10 cm 2)和全尺寸梯形(1个\times 0.5 m2)三重GEM原型的设计和构造。在探测器组装期间,测试了用于拉伸GEM箔的不同技术。将显示小型和大型原型的X射线测量结果和CERN SPS的测试光束活动结果。初步模拟研究的预期μ子重建和触发性能的建议升级μ子系统将报告。

英文摘要:

At present, part of the forward RPC muon system of the CMS detector at the CERN LHC remains uninstrumented in the high-ηregion. An international collaboration is investigating the possibility of covering the 1.6 < |η| < 2.4 region of the muon endcaps with large-area triple-GEM detectors. Given their good spatial resolution, high rate capability, and radiation hardness, these micro-pattern gas detectors are an appealing option for simultaneously enhancing muon tracking and triggering capabilities in a future upgrade of the CMS detector. A general overview of this feasibility study will be presented. The design and construction of small (10\times10 cm2) and full-size trapezoidal (1\times0.5 m2) triple-GEM prototypes will be described. During detector assembly, different techniques for stretching the GEM foils were tested. Results from measurements with x-rays and from test beam campaigns at the CERN SPS will be shown for the small and large prototypes. Preliminary simulation studies on the expected muon reconstruction and trigger performances of this proposed upgraded muon system will be reported.
