Abstract

Resistive Plate Chamber detectors [1], [2] play a crucial role in triggering events with muons in the ATLAS central region [3]. In view of the High Luminosity LHC program, this system is facing a significant upgrade. In the next few years, 226 triplets of new generation RPCs will be installed in the innermost region of the ATLAS Muon Barrel Spectrometer while 80 triplets in the outer Muon Spectrometer (MS) region, increasing the number of tracking layers from 6 to 9, doubling the trigger lever arm and increasing the coverage. The new Barrel Inner RPCs (BI-RPC) have an improved rate capability up to 10 kHz/cm

to withstand the HL-LHC conditions (CER 2017). This contribution will present an overview of the ATLAS RPC Phase II project, the qualification of gas volumes and read out planes, the present status of RPC singlets production and tests.

高亮度LHC时代的ATLAS RPC第二阶段升级

电阻板室探测器[1]，[2]在ATLAS中心区域[3]的μ子触发事件中起着至关重要的作用。鉴于高亮度LHC计划，该系统面临着重大的升级。未来几年，ATLAS μ子桶谱仪最内层区域将安装226个新一代rpc三联体，外层μ子谱仪（MS）区域将安装80个三联体，将跟踪层数从6层增加到9层，将触发杠杆臂增加一倍，增加覆盖范围。新的桶内rpc （BI-RPC）具有提高的速率能力，最高可达10 kHz/cm2，以承受HL-LHC条件（CER 2017）。这篇文章将概述ATLAS RPC二期项目，天然气体积和读出平面的资格，RPC单线生产和测试的现状。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
