SUMMARY:Speaker: Gianpaolo Carosi (LLNL) - Title: Tuning into Dark Matter with the ADMX experiment
DESCRIPTION:Research Progress Meeting \nDate: November 6\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Gianpaolo Carosi (LLNL) \nTitle: Tuning into Dark Matter with the ADMX experiment \nAbstract: The primordial axion remains one of the best solutions to both dark matter and the strong-CP problem (or why the neutron doesn’t have a measurable electric-dipole moment). The Axion Dark Matter Experiment (ADMX)\, which started at Lawrence Livermore National Laboratory in the mid-1990s\, is the DOE Flagship search for these particles in the micro-eV mass range. The experiment uses tunable resonant cavities in a large static magnetic field to enhance the conversion of dark matter axions to detectable microwaves in the GHz range. Quantum-limited amplifiers based on superconducting Josephson Junction circuits are critical to allow the search to be sensitive enough to rapidly scan the frequencies where the axion may exist. Here I will describe the detection strategy of ADMX\, the progress made so far and outline the potential next phase of the experiment dubbed ADMX-Extended Frequency Range (ADMX-EFR). I will also discuss LLNL’s involvement in the nascent BREAD broadband axion search. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Xiaochen Ni (University of Washington) - Title: Development of TopmetalSe: CMOS/aSe Hybrid Detectors for Neutrino Physics
DESCRIPTION:Research Progress Meeting \nDate: November 20\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Xiaochen Ni (University of Washington) \nTitle: Development of TopmetalSe: CMOS/aSe Hybrid Detectors for Neutrino Physics \nAbstract: The Selena experiment couples an amorphous selenium (aSe) ionization target to a complementary metal–oxide–semiconductor (CMOS) pixel array as an imaging detector for next-generation neutrino physics. Hybrid a-Se/CMOS detectors provide a unique combination of high-Z stopping power\, direct charge conversion\, and fine-pitch pixel imaging. These properties enable precise reconstruction of ionization tracks with excellent spatial resolution\, allowing for low-background measurements with advanced event classification. In this talk\, I will present Selena’s capabilities for a neutrinoless double-beta decay search and share the ongoing detector R&D\, including the design\, fabrication\, and characterization of its first prototype pixel array\, TopmetalSe\, produced in the SkyWater 130 nm open-source CMOS process. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Mun Jung Jung (University of Chicago) - Title: Quasielastic–like Interactions of Muon Neutrinos in SBND
DESCRIPTION:Research Progress Meeting \nDate: November 25\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Mun Jung Jung  (University of Chicago) \nTitle: Quasielastic–like Interactions of Muon Neutrinos in SBND \nAbstract: The Short-Baseline Near Detector (SBND)\, the near detector of the Short-Baseline Neutrino (SBN) program at Fermilab\, has completed a successful Run 1\, delivering an unprecedented dataset of neutrino-argon interactions. One of the first targets for SBND is the muon neutrino charged-current quasielastic–like channel\, the dominant exclusive topology in SBN and a sensitive probe of nuclear effects. In this talk\, I’ll present progress toward the first SBND physics results and discuss how the quasielastic-like channel can be studied to test interaction models and lay the foundation for the broader neutrino-nucleus interaction and oscillation physics program at SBND and SBN. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037
