| Description | Speaker: Teal Pershing, LLNL Title: The ANNIE Experiment: Measuring the neutron multiplicity of neutrino-nucleus interactions Host: Svoboda Zoom: TBD Abstract:Accurate modeling and tagging of inelastic charged-current neutrino interactions is critical to numerous physics measurements, including proton decay, neutrino oscillation parameter measurements, and neutrino interaction cross-section measurements. One known indicator of a neutrino interaction’s inelasticity is the presence of final-state neutrons, which are often challenging to detect. The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a gadolinium-doped water Cherenkov detector which is sensitive to final-state neutrons, and will measure the neutron multiplicity of neutrino charged-current interactions. ANNIE will also demonstrate the first use of Large Area Picosecond PhotoDetectors (LAPPDs) on a neutrino beam line for improved event reconstruction. This seminar will provide an overview of the ANNIE experiment and the physics motivating ANNIE’s neutron multi- plicity measurement. The experimental results from ANNIE’s background characterization will be presented, as well as the first calibration and neutrino beam data from ANNIE. |
