EXO-200实验用单相液体氙探测器寻找136的无中微子双β衰变。它在一个超低本底时间投影室中使用了110公斤的80.6%浓缩液体氙的有效质量，并带有电离和闪烁探测和读出。本文介绍了探测器操作所需的各种支持系统的设计和性能，包括低温、氙处理和控制。该系统的新功能是由需要保护薄壁检测器室包含液体氙，以实现高化学纯度的氙，并保持整个检测器的热均匀性。
The EXO-200 experiment searched for neutrinoless double-beta decay of 136 Xe with a single-phase liquid xenon detector. It used an active mass of 110 kg of 80.6%-enriched liquid xenon in an ultra-low background time projection chamber with ionization and scintillation detection and readout. This paper describes the design and performance of the various support systems necessary for detector operation, including cryogenics, xenon handling, and controls. Novel features of the system were driven by the need to protect the thin-walled detector chamber containing the liquid xenon, to achieve high chemical purity of the Xe, and to maintain thermal uniformity across the detector.
