Abstract
Abstract
The Accelerator Neutrino Neutron Interaction Experiment
(ANNIE) is a 26-ton water Cherenkov neutrino detector installed on
the Booster Neutrino Beam (BNB) at Fermilab. Its main physics goals
are to perform a measurement of the neutron yield from
neutrino-nucleus interactions, as well as a measurement of the
charged-current cross section of muon neutrinos. An equally
important focus is the research and development of new detector
technologies and target media. Specifically, water-based liquid
scintillator (WbLS) is of interest as a novel detector medium, as it
allows for the simultaneous detection of Cherenkov light and
scintillation. This paper presents the deployment of a 366 L WbLS
vessel in ANNIE in March 2023 and the subsequent detection of both
Cherenkov light and scintillation from the WbLS. This
proof-of-concept allows for the future development of reconstruction
and particle identification algorithms in ANNIE, as well as
dedicated analyses within the WbLS volume, such as the search for
neutral-current events and the hadronic scintillation component.
