Cyclotrons as Drivers for Precision Neutrino Measurements

Figure 14

The event energy distributions for signal and background of the DAE𝛿ALUS@Hyper-K running scenario with sin²2𝜃₁₃=0.10. Black, green, and violet histograms show signals for 𝛿_CP=0, 45^∘ and −45^∘. The blue histogram shows the intrinsic 𝜈_𝑒 beam-on background. The red histogram shows the beam-off backgrounds. (a) and (b) show events from the near (1.5 km) and middle (8 km) accelerators. (c) shows events from the far (20 km) accelerator.
