ANNIE in 10 Minutes

The Accelerator Neutrino Nucleus Interaction Experiment (ANNIE) has recently completed its first phase of data taking. The main physics goals of ANNIE, to be completed in the upcoming Phase II, are a measurement of the neutron abundance from neutrino-nucleus interactions, and a charged-current inclusive cross-section measurement on Oxygen. To achieve these goals the collaboration will use Gadolinium-loaded water to detect neutrons from a neutrino beam, and Large Area Picosecond Photodetectors (LAPPDs) for precise event reconstruction. Phase I used a simplified detector to perform measurements of the neutron flux from upstream interactions, a relevant background for Phase II measurements. This talk will present the results obtained and discuss the progress towards Phase II, scheduled to begin taking data in Fall 2018.
