Double Chooz 在研究 $\bar \nu_e$ 消失的现代基于反应堆的中微子实验中是独一无二的，因为可以在所有反应堆关闭的情况下收集数据。在本文中，我们提供了反应堆停运 7.53 天的数据。应用与 Double Chooz 反应堆振荡分析中使用的相同选择标准，获得测量的背景率为 1.0$\pm$0.4 事件/天。振荡分析中使用的偶发、宇宙源 $\beta$-$n$ 发射同位素、宇宙 μ 子快中子和停止 $\mu$ 衰变的背景模型被证明在不确定性范围内是正确的。提供了事件的运动学分布，这些事件主要是宇宙射线产生的相关背景事件。背景速率根据另外两个基于反应堆的振荡实验（大亚湾和雷诺）的屏蔽深度进行缩放。
Double Chooz is unique among modern reactor-based neutrino experiments studying $\bar \nu_e$ 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 1.0$\pm$0.4 events/day is obtained. The background model for accidentals, cosmogenic $\beta$-$n$-emitting isotopes, fast neutrons from cosmic muons, and stopped-$\mu$ 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.
