Design of hardware interfaces for the LHC Phase-2 CMS ECAL Barrel Safety System

Abstract

The CMS Electromagnetic Calorimeter (ECAL) uses lead tungstate scintillating crystals to measure the energy of electrons and photons produced at the Large Hadron Collider (LHC). The High Luminosity upgrade of the LHC (HL-LHC) at CERN during the LHC Long Shutdown 3 imposes significant challenges for its experiments. The higher luminosity changes the environmental conditions in which the ECAL detector will operate. In this contribution the upgrade plans and preliminary designs to accommodate the new operational requirements of the CMS ECAL Barrel Safety System are summarized, including the design and development of hardware components for Resistance Temperature Detector (RTD) interfacing and the interlock control.
