Innovative Standalone Massive Channel Temperature Monitoring System For Cms Detector

Abstract

Compact Muon Solenoid (CMS) experiment has been preparing for Upgrade-2 and High Luminosity-Large Hadron Collider (HL-LHC) projects during Long Shutdown 2 (LS2) by replacing and enhancing electronics and the components of its detector. The Upgrade-2 project will implement high intensities in the collisions, which results in a highly integrated luminosity of about 2500 f b−1 at the heart of the detector. Moreover, the experiment will gather more data with the HL-LHC, which enables an additional integrated luminosity by a factor of 10 beyond the current luminosity value of the Large Hadron Collider (LHC) after 2027. Higher luminosity values bring about higher temperature onto electronics of the detector, therefore controlling and monitoring the temperature around the detector environment under challenging operating conditions plays a crucial role. This temperature monitoring has been fulfilled by the Programmable Logic Controller (PLC) up to this point in time. However, a new and optimum monitoring system is made essential because PLC-based monitoring is more expensive and takes much more place. The work presented in this Tez addresses the above-mentioned issues and proposes a novel temperature monitoring system using embedded systems. In this approach, we developed a Massive Temperature Monitoring System (MTRS), including sensor choices, designing readout circuitry, hardware and software implementations, and optimizing the issues to have arisen, as well as providing communication between MTRS and Detector Control System (DCS) via Open Platform Communications Unified Architecture (OPC UA) server. This dissertation discusses the reasons why the MTRS is essential for the future upgrades of the detector and furnishes the ways of embedded-based approach.
