SUMMARY:Speaker: Livio Calivers (University of Bern) - Title: Light Detection for Modular Liquid Argon Neutrino Detectors: From Concept to Beam Data in the DUNE Near Detector
DESCRIPTION:Research Progress Meeting \nDate: January 8\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Livio Calivers\, University of Bern \nTitle: Light Detection for Modular Liquid Argon Neutrino Detectors: From Concept to Beam Data in the DUNE Near Detector \nAbstract: The Deep Underground Neutrino Experiment (DUNE) aims to perform precision measurements of neutrino oscillations\, which require stringent control of systematic uncertainties at the Near Detector. A major challenge arises from the severe interaction pile-up in liquid-argon time projection chambers operating near the origin of the intense neutrino beam. This talk describes how fast scintillation-light detection is exploited to enhance event reconstruction and interaction timing in the modular Liquid Argon Near Detector (ND-LAr). The design of the ArCLight system is presented—a fully dielectric\, SiPM-based light detector integrated directly into the TPC drift field\, providing efficient photon collection with minimal inactive material. Results from the DUNE 2×2 Demonstrator operated in the NuMI beam at Fermilab include the observation of neutrino interactions and a demonstrated sub-4 ns timing resolution\, sufficient to resolve the accelerator bunch structure and enable in-spill interaction separation. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239
