Description
The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton gadolinium-doped water Cherenkov detector located on the Booster Neutrino Beam at Fermilab. Its primary goal is to measure neutron yields from neutrino-nucleus interactions as a function of lepton kinematics, thereby advancing our understanding of neutrino interactions and reducing systematic uncertainties in neutrino experiments. ANNIE also serves as a test bed for novel detector technologies, including the Large Area Picosecond Photodetector (LAPPD), which provides sub-100 picosecond timing and high spatial resolution for light detection. ANNIE has achieved the first successful detection of muon neutrino interactions using LAPPDs, demonstrating their promise for precision event reconstruction in neutrino physics. In addition, the experiment has conducted the first tests of Water-based Liquid Scintillator (WbLS) as a novel detection medium. This talk will present the current status of the experiment, highlight LAPPD-based event reconstruction techniques, and share preliminary results from the recent analysis of neutrino data.
