The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) aims at measuring the neutron abundance in the final state of neutrino-nucleus interactions. This measurement 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. The ANNIE detector uses 30 tons of gadolinium-loaded water to enhance the neutron-caputre cross section. It is instrumented with a combination of conventional photomultipliers and novel Lare Area Picosecond Photodetectors (LAPPDs). After a background characterization phase, the detectors has been installed in the Booster Neutrino beam at Fermilab and has begun taking data. This presentation will show early data from the ANNIE experiment.
