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.
