Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

indico search will be reestablished in the next version upgrade of the software: https://getindico.io/roadmap/

Description

The primary physics goal of Phase II of the Accelerator Neutrino Neutron Interaction Experiment (ANNIE), is to measure the nuclear final states from neutrino interactions in water, with a particular focus on the production and multiplicity of final-state neutrons. The detector sits in the SciBooNE Hall, on Fermilab's Booster Neutrino Beam (BNB). The upgraded detector will have ~125 photomultiplier tubes in Phase II, increasing our detection efficiency for neutron captures, and will also incorporate at least five Large Area Picosecond Photodetectors (LAPPDs). ANNIE will be the first application of a multi-LAPPD system in a physics measurement and the introduction of these LAPPDs will provide the precise vertex and track reconstruction capabilities required to achieve our physics goals. In this talk, we discuss the simulation of beam neutrino interactions in the Phase II detector. Then, using these simulations, we demonstrate the increase we can achieve in the precision of our vertex and track resolution with optical coverage from five LAPPDs, in addition to photomultiplier tubes, over coverage from photomultiplier tubes alone.
