2023 Departmental Poster Competition

During the next LHC long shutdown 3 (2024-2026), the Compact Muon Solenoid (CMS) experiment will replace its current endcaps with a high granularity calorimeter (HGCAL) that comprises ~6M silicon cells and ~400K scintillator tiles. HGCAL will operate at -30 C in order to keep electronics noise low and charge collection efficiency as high as possible. TTU is one of the Module Assembly Centers for these modules. We present the current design, material choices and the details of the assembly process.
