  1. 21. Study and mitigation of discharges in CMS triple-GEM detectors
    Dr Jeremie Alexandre Merlin (KCMS -Hanyang University & University of Seoul)
    10/11/2023, 09:25
    Oral

    The GEM project of CMS encompasses the development, construction, and operation of three new triple-GEM detector systems, GE1/1, GE2/1 and ME0, for the upgrade of the forward muon spectrometer. The development of these systems and the operation of multiple advance-design demonstrators installed in the experiment, allowed for thorough studies of the gas breakdown effect that typically leads to...

  2. 34. Numerical simulation of charging up, accumulation of space charge and formation of discharges
    Prof. Nayana Majumdar (Saha Institute of Nuclear Physics), Dr Purba Bhattacharya (Adamas University, Kolkata, India)
    10/11/2023, 09:50
    Oral

    Aging and stability of gaseous ionization detectors are intricately related to charging up, accumulation of space charge and formation of discharges. All these phenomena, in their turn, depend on the dynamics of charged particles within the device. Because of the large number of particles involved and their complex interactions, the dynamic processes of generation and loss of charged...

  3. 8. Study of discharges observed in the CMS GE1/1 station during LHC Run-3
    Simone Calzaferri (Università degli studi di Pavia - INFN Pavia)
    10/11/2023, 10:15
    Oral

    Since July 2022, GE1/1, the first station using Gas Electron Multiplier (GEM) technology in the Compact Muon Solenoid (CMS) experiment, has been participating in the data-taking in proton-proton collisions. This station is the first of three (GE1/1, GE2/1 and ME0) planned to be installed in CMS, to cope with the challenging conditions given by the upgrade of luminosity of the Large Hadron...

  4. 50. Spark Protection System for the sPHENIX TPC GEMs
    Julian Driebeek (Stony Brook University)
    10/11/2023, 11:00
    Oral

    The sPHENIX experiment is currently under commissioning at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab (BNL). The Time Projection Chamber (TPC) serves as a tracking detector for the experiment. The sPHENIX TPC uses a stack of four Gas Electron Multipliers (GEM’s) as a gain stage in a reduced ion back-flow configuration. In non-ideal conditions, the high voltage across...
