Direct Measurement of Backgrounds using Reactor-Off Data in Double Chooz
Abstract
Double Chooz is unique among modern reactor-based neutrino experiments studying disappearance in that data can be collected with all reactors off. In this paper, we present data from 7.53 days of reactor-off running. Applying the same selection criteria as used in the Double Chooz reactor-on oscillation analysis, a measured background rate of 1.00.4 events/day is obtained. The background model for accidentals, cosmogenic --emitting isotopes, fast neutrons from cosmic muons, and stopped- decays used in the oscillation analysis is demonstrated to be correct within the uncertainties. Kinematic distributions of the events, which are dominantly cosmic-ray-produced correlated-background events, are provided. The background rates are scaled to the shielding depths of two other reactor-based oscillation experiments, Daya Bay and RENO.
