摘要
RELICS（REactor neutrino LIquid xenon Coherent elastic Scattering）实验旨在检测来自堆芯反中子的协同弹性中子-核散射。为验证探测器概念并确保全规模实验的技术可靠性，设计、构建并运行了一个专用原型机。本工作概述了该原型机的设计、构造及运行性能，重点论及其主要子系统，包括TPC、 cryogenic及氦-氕纯化系统、慢速控制及数据采集。运行期间，探测器证明了达到RELICS物理计划所需亚 keV 能量阈值的能力，这体现在测得的单个电子增益为 （统计）PE/e，以及成功探测到 Ar 的 0.27 keV L 壳衰变事件。此外，还开发并验证了必需的数据分析技术与仿真框架，为未来RELICS运行奠定了方法论基础。该原型机的成功建造与运行确认了核心技术的可行性，为最终RELICS探测器提供了关键实验依据。
