3WJB.00001: The ePIC Detector: Overview Invited Speaker: Charlotte Van Hulse The electron-proton/ion collider (ePIC) detector will be the first detector at the upcoming electron-ion collider (EIC) at Brookhaven National Lab. The design of the detector is determined by the various physics goals of the EIC programme, which include addressing the origin of the nucleon spin, the three-dimensional structure of the nucleon, the study of saturation effects, and the study of hadronisation. An overview of the detector design and the expected performance, based on GEANT4 simulation studies, will be presented. |

3WJB.00002: Advanced Calorimetry R&D for the ePIC Detector at the EIC Invited Speaker: Igor Korover The Electron-Ion Collider is poised to be a unique machine that will significantly extend our knowledge of Quantum Chromodynamics (QCD). The combination of high luminosity and high beam polarization will provide unprecedented precision for studying the fundamental structure of hadrons and nuclei. To deliver on the EIC physics program, the ePIC collaboration was formed with the goal of designing and building a detector capable of addressing the full range of the EIC science program. Calorimetry, both electromagnetic and hadronic, are crucial subsystems of the ePIC detector and have a significant impact on the detector design. These subsystems are being designed and developed by the collaboration to meet the required precision. As a hermetic detector, it is crucial to optimize different regions around the interaction point for measuring various particles/jets with appropriate resolution and be able to separate them from the background. In this talk, I will describe the different calorimeter subsystems and provide the most recent updates on their current status, with emphasis on the new features in ePIC that advance the state-of-the-art in calorimetry. |

3WJB.00003: AC-LGAD Detector R&D for the EIC ePIC Experiment Invited Speaker: Kenta Shigaki The Time of Flight (ToF) subsystem is a key device of particle identification at the EIC ePIC experiment, especially in the low transverse momentum region up to a few GeV/c. The flight path for the ToF in the central barrel is less than 70 cm due to the compact design of the whole detector. It hence requires an exceptionally good timing resolution of ~30 ps, as well as a fine segmentation to supplement the tracking and a thin material budget for the detectors behind. The technology choice is AC coupled Low Gain Avalanche Diode (AC-LGAD). |
