The ANNIE experiment — •Michael Nieslony, David Maksimovic, Daniele Guffanti, and Michael Wurm for the ANNIE collaboration — Johannes Gutenberg University, Mainz, Germany

The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a Gadolinium doped water Cherenkov detector located in the Booster Neutrino Beam at Fermilab with the primary goal of measuring the final state neutron multiplicity of neutrino-nucleus interactions. ANNIE will make use of pioneering photodetectors called Large Area Picosecond Photodetectors (LAPPDs) with less than 100 picosecond time resolution to enhance its reconstruction capabilities and demonstrate the feasibility of this technology as a new tool in high energy physics. This talk will present an overview of recently taken ANNIE beam commissioning and calibration data and outline the framework for the upcoming neutron multiplicity analysis. Furthermore, additional future R&D efforts involving the use of the novel detection medium of water-based Liquid Scintillators will be briefly highlighted.
