Measurement of the 8B Solar Neutrino Flux in the Partial Fill Phase of the SNO+ Experiment

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. Due to interruptions from the COVID-19 pandemic, filling of the detector with liquid scintillator was paused from April to October of 2020, allowing an extended period of stable data-taking with the detector about half-filled with scintillator. This work will discuss the measurement of the Boron-8 solar neutrino flux during this phase of the experiment. Preliminary results for a similar measurement in the now fully-filled detector will also be shown and the outlook for future solar neutrino studies with SNO+ will be discussed.
