Abstract:
The FCC-ee, endorsed as CERN's next flagship project, will operate as a precision Higgs and electroweak factory at centre-of-mass energies up to 365 GeV, demanding detectors with excellent energy resolution, high granularity, and large dynamic range for particle-flow reconstruction and precision measurements. This seminar presents ALLEGRO (A Lepton collidEr detector with Granular Read-Out), a detector concept distinguished by a highly-granular noble-liquid sampling electromagnetic calorimeter. Building on the proven technology of liquid argon and krypton calorimetry successfully deployed in DØ, ATLAS, and NA62, ALLEGRO exploits advances in multi-layer printed circuit board manufacturing to achieve almost arbitrarily high readout granularity. Multi-layer PCB electrodes between noble-liquid gaps and lead absorber plates enable four-dimensional imaging of electromagnetic showers, allowing machine-learning algorithms and particle-flow reconstruction to be fully exploited. The talk focuses on the ECAL design, including the PCB readout electrode innovations, mechanical engineering, cryostat integration, and electronics options, and discusses the ongoing R&D within the DRD6 collaboration and the test-beam prototype roadmap.
Speaker Bio:
Zuchen Huang earned his Ph.D. from the University of Manchester in 2024 and is presently a postdoctoral researcher at IJCLab (Laboratoire de Physique des 2 Infinis Irène Joliot-Curie) in Orsay, France. He is active in both data analysis and detector development: within the ATLAS collaboration, he focuses on Standard Model electroweak measurements, particularly diboson production; within the ALLEGRO collaboration, he contributes to electrode R&D and ECAL simulation.
