The Hadron Calorimeter (HCAL) in the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) was recently upgraded for Run 3 to introduce depth segmentation and online timing measurements, expanding the physics capabilities. In particular, the augmentation of the calorimeter information at the hardware trigger level enables quick identification and recording of long-lived...
The CMS electromagnetic calorimeter (ECAL) is a high resolution crystal calorimeter operating at the CERN LHC. The ECAL trigger system employs fast digital signal processing algorithms to measure the energy and timing of ECAL energy deposits recorded during LHC collisions. These trigger primitives are transmitted to the Level-1 trigger system at the collision rate of 40 MHz, and are combined...
The CMS Electromagnetic Calorimeter (ECAL) is the largest calorimeter operating in a high energy physics experiment. During the course of the LHC Run 1, Run 2, and Run 3, ECAL has made essential contributions to the CMS physics program by precisely measuring the energy, position, and time of arrival of photons and electrons, and of hadronic jets. Among the masterpieces of physics results...
The CMS experiment at LHC has a 15 year experience with the energy measurement of electrons and photons produced in collisions of high-luminosity high-energy colliders with a homogeneous electromagnetic calorimeter. The PbWO$_4$ crystal calorimeter must operate at high rate in a harsh radiation environment: changes in detector response need to be corrected for and dedicated techniques are used...
