论文摘要
反应堆抗瑞氏菌的强烈通量提供了一种独特的可能性，可以探测弹性中微子散射在原子核上的完全相干特征。在这方面，探测器面临着在最大值中注册一些keV的微小后坐力的挑战。圆锥实验的安装在德国布罗克多夫的核电站的反应堆芯中以17.1 m的距离安装，旨在通过使用带有子Kev能量阈值的四个1 kg尺寸接触族检测器来检测这种中微子相互作用通道。该报告描述了设计，研发以及这些检测器的最终产生的独特规格。它证明了它们在实验室条件下的调试期间以及在2018年4月1日开始在反应堆站点运行的头两年中获得的出色电子性能。它突出了不同检测器参数的长期稳定性以及Conus Shield设置内锗探测器的背景水平所达到的背景水平。
Intense fluxes of reactor antineutrinos offer a unique possibility to probe the fully coherent character of elastic neutrino scattering off atomic nuclei. In this regard, detectors face the challenge to register tiny recoil energies of a few keV at the maximum. The CONUS experiment was installed in 17.1 m distance from the reactor core of the nuclear power plant in Brokdorf, Germany, and was designed to detect this neutrino interaction channel by using four 1 kg-sized point contact germanium detectors with sub-keV energy thresholds. This report describes the unique specifications addressed to the design, the research and development, and the final production of these detectors. It demonstrates their excellent electronic performance obtained during commissioning under laboratory conditions as well as during the first two years of operation at the reactor site which started on April 1, 2018. It highlights the long-term stability of different detector parameters and the achieved background levels of the germanium detectors inside the CONUS shield setup.
