High-Resolution Endcap Electromagnetic Calorimeter for Higgs Boson Detection

The Endcap Electromagnetic Calorimeter is a high-resolution crystal detector designed to discover the Higgs boson. Utilizing dense lead tungstate crystals, it effectively stops electrons and photons, emitting scintillation light detected by Vacuum Phototriodes (VPT). The calorimeter comprises 14,648 crystals supported by an innovative mechanical structure known as the EndcapSupercrystal, which houses groups of 25 crystals and VPTs. Built through international collaboration, this system combines advanced mechanical engineering and robust design principles to enhance particle physics research capabilities.
