Description
The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a neutrino detector at the Booster Neutrino Beam (BNB) at Fermilab. It is a 26-ton Gadolinium-loaded water Cherenkov detector designed to measure CC interaction cross-sections and neutron multiplicity. In addition, ANNIE serves as a testbed for novel detector technologies amongst which is Water-based Liquid Scintillator (WbLS). WbLS is a novel detection medium that allows the simultaneous detection of scintillation and Cherenkov light. WbLS also allows new techniques of isotope loading in liquid scintillator to enhance detector sensitivity. To test the detection capabilities of WbLS, a 366 L cylindrical vessel, called SANDI, filled with WbLS was deployed in ANNIE in 2023 for two months. The successful observation of both scintillation and Cherenkov light in ANNIE corresponds to a proof-of-concept for the hybrid event detection concept. Additionally, SANDI was redeployed with Gd-loaded WbLS in fall 2024 to investigate the enhanced neutron detection capabilities. Here, an overview of the WbLS activity in ANNIE is presented.
