Measurement of the ⁸B Solar Neutrino Flux in the Full Fill Phase of the SNO+ Detector

SNO+ is a kiloton-scale, multipurpose neutrino experiment located in Sudbury, Ontario, Canada. Initially filled with an ultrapure water target, SNO+ is now filled with the liquid scintillator linear alkyl benzene (LAB) loaded with the wavelength shifter 2,5-Diphenyloxazole (PPO), and will soon be loaded with Tellurium-130 to study neutrinoless double beta decay. Filling of the detector with liquid scintillator completed in April 2022, with a deployed mass of 780 kilotons of scintillator with final PPO concentration of 2.2 g/L of LAB. The favorable light yield, timing and optical properties of this scintillator cocktail allow for various interesting neutrino signals to be studied, including solar neutrinos. This work will discuss the measurement of the Boron-8 solar neutrino flux during this phase of the experiment, which continued until June 2023, when the scintillator cocktail was further optimized. The outlook for future solar neutrino studies with SNO+ will also be discussed.
