Crucial questions about solar neutrinos remain unanswered.   Our knowledge of stellar fusion processes and neutrinos themselves is incomplete.  Neutrino detectors such as Super-Kamiokande have the exposure needed, but backgrounds are limiting.  A leading background is the beta decays of isotopes produced by cosmic-ray muons and their secondary particles, which initiate nuclear spallation reactions.  I will discuss my comprehensive studies of the spallation backgrounds, from calculating their production rates, to understanding their production mechanisms, to how to implement better background rejection methods.  I will also discuss how our work will enable better probes of both solar and neutrino physics.
