SoLid合作开发了一种新的探测器技术，可以在比利时BR 2反应堆附近的表面水平探测电子反中微子。2015年部署了一个288公斤的原型探测器，并在反应堆运行期间和反应堆关闭期间收集数据。还对伽马和中子源进行了专门的校准活动。本文介绍了原型探测器的结构，其质子含量和稳定性的控制，其操作在几个月后，在BR 2反应堆现场部署的一段时间。所有探测器单元都提供足够的光输出，以实现优于20%/MeV的目标能量分辨率。探测器跟踪μ子的能力被用来均衡大量通道的光响应，精度为3%，并证明能量尺度随时间的稳定性。粒子识别的脉冲形状歧视的基础上证明与校准源。尽管由于触发限制，中子探测效率较低，但反应堆现场的主要背景已确定，并在主要实验的屏蔽策略中考虑到了这一点。用该原型获得的结果证明在最终探测器的设计优化中是必不可少的。
The SoLid collaboration has developed a new detector technology to detect electron anti-neutrinos at close proximity to the Belgian BR2 reactor at surface level. A 288 kg prototype detector was deployed in 2015 and collected data during the operational period of the reactor and during reactor shut-down. Dedicated calibration campaigns were also performed with gamma and neutron sources. This paper describes the construction of the prototype detector with a high control on its proton content and the stability of its operation over a period of several months after deployment at the BR2 reactor site. All detector cells provide sufficient light yields to achieve a target energy resolution of better than 20%/√E(MeV). The capability of the detector to track muons is exploited to equalize the light response of a large number of channels to a precision of 3% and to demonstrate the stability of the energy scale over time. Particle identification based on pulse-shape discrimination is demonstrated with calibration sources. Despite a lower neutron detection efficiency due to triggering constraints, the main backgrounds at the reactor site were determined and taken into account in the shielding strategy for the main experiment. The results obtained with this prototype proved essential in the design optimization of the final detector.
