Description
The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton Gd-loaded water Cherenkov detector installed in the Booster Neutrino Beam (BNB) at Fermilab. It aims to accurately detect and understand neutrino-nucleus interactions by measuring the resulting neutron multiplicity. ANNIE is also the first neutrino physics experiment to deploy Large Area Picosecond PhotoDetectors (LAPPDs) which will enable improved vertex resolution. To achieve the physics goals of the second phase of ANNIE, we must characterize the neutron capture efficiency throughout the detector volume, establish the beam-related neutron background and determine the vertex resolution enabled with LAPPDs. This talk will describe progress in all of these aspects of the calibration and analysis for the ANNIE experiment.
