Abstract
In preparation for the Phase-II upgrade for the High-Luminosity LHC program, 72 improved Resistive Plate Chambers (iRPC) will be installed in the third and fourth endcap disks of the Compact Muon Solenoid detector during the annual technical stop 2024. This new generation of RPC detectors will operate in a low-angle momentum (extending RPC coverage from pseudorapidity = 1.9 to 2.4), in a high radiation environment, and will bring a better space and time resolution for this challenging region. To ensure proper performance, iRPC chambers undergo a series of quality control (QC) tests at each stage of the assembly chain. These tests include QC1 for the basic components, QC2 for chamber elements such as gaps and cooling, QC3 for evaluating the full chamber performance after production, which includes noise, efficiency, current, lastly QC4 for the final validation of the chambers. In this work we present the different QC stages and discuss test results for the newly built iRPCs at the assembly sites.
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.
