Description
The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton Gadolinium-loaded, water-based detector located on the Fermilab Booster Neutrino Beam (BNB) with the goals of: (1) measuring the neutron abundance in the final state of neutrino-nucleus interactions, and (2) demonstrating advanced neutrino detection technology. The physics measurement of ANNIE will have a direct impact on our understanding of neutrino interactions and will lead to a better reduction of systematic errors and an improvement of signal-background discrimination in future large neutrino detectors. ANNIE is now the first Gd-loaded water Cherenkov detector deployed on a neutrino beam and will soon be the first deployment of Large Area Picosecond Photo-Detectors (LAPPDs). ANNIE has recorded very first neutrino candidate events at the beginning of 2020. This presentation will show early data from the ANNIE experiment.
