Determining Reactor Neutrino Flux

Understand

Flux is an important source of uncertainties for a reactor neutrino experiment.

• It is determined from thermal power measurements, reactor core simulation, and knowledge of neutrino spectra of fuel isotopes.
• Past reactor neutrino experiments have determined the flux to (2-3)% precision.
• Precision measurements of mixing angle $\theta_{13}$ by reactor neutrino experiments in the coming years will use near-far detector configurations.
