论文摘要
作为紧凑型MUON电磁实验II期升级程序的一部分，将安装新的电阻板室。在大型强子对撞机的高光度阶段，该区域的背景条件预计会很高，因此已经提出了使用新的前端电子设备的RPC设计改进，以维持更高的速率能力和更好的时间分辨率。在前端电子设备中使用了一项新技术，导致几个FC的顺序可实现的阈值非常低。改进RPC的设计至关重要的是二维读数的能力，以改善空间分辨率，这主要是由触发需求激励。在这项工作中，基于在带有两个嵌入式正交读数条的实数原型室的数据上，提出了这项二维读数的第一个性能结果。此外，讨论了对若子簇大小作为石墨电阻率的函数的专门研究。
As part of the Compact Muon Solenoid experiment Phase-II upgrade program, new Resistive Plate Chambers will be installed in the forward region. High background conditions are expected in this region during the high-luminosity phase of the Large Hadron Collider, therefore an improved RPC design has been proposed with a new front-end electronics to sustain a higher rate capability and better time resolution. A new technology is used in the front-end electronics resulting in very low achievable thresholds of the order of several fC. Crucial in the design of the improved RPC is the capability of a two-dimensional readout in order to improve the spatial resolution, mainly motivated by trigger requirements. In this work, the first performance results towards this two-dimensional readout are presented, based on data taken on a real-size prototype chamber with two embedded orthogonal readout strips. Furthermore, dedicated studies of the muon cluster size as a function of the graphite resistivity are discussed.
