Description
The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton gadolinium doped water Cherenkov detector on-axis of the Booster Neutrino Beam (BNB) at Fermilab. Its main goal is to measure the final state neutron multiplicity of neutrino-nucleus interactions to improve the systematic uncertainties of next-generation long baseline neutrino experiments. A key milestone for ANNIE is the deployment of the Large Area Picosecond Photodetectors (LAPPD), a novel detector technology with a timing resolution of <100ps and a sub-centimeter spatial resolution. ANNIE is the first large-scale high energy physics experiment to deploy such a light sensor. This poster will give an update on the status of the LAPPD testing as well as first results from the deployed LAPPDs.
