标题： Malter-Driven Electron Emission as a Source of Noise in LXe TPCs

摘要： 持久的单电子发射（“热点”）已在多个液氙（LXe）时间投影室（TPCs）中被观察到，通常在电离事件后长时间存在。 尽管通常以操作术语进行讨论，但这种行为与由电阻氧化物表面离子积累触发的Malter型发射一致。 在本说明中，我们讨论此类效应，并建议材料选择和设计策略以减轻未来探测器中的这些影响。 这一机制对于旨在实现超低能阈值的实验尤其相关，因为即使小的背景发射也可能限制灵敏度。 显示英文摘要

摘要： Persistent single-electron emission ("hot spots") has been observed in multiple liquid xenon (LXe) time projection chambers (TPCs), often persisting long after ionizing events. Although typically discussed in operational terms, the behavior is consistent with Malter-type emission triggered by ion accumulation on resistive oxide surfaces. In this note, we discuss such effects and recommend material choices and design strategies to mitigate them in future detectors. This mechanism is especially relevant to experiments targeting ultra-low energy thresholds, where even small background emissions can limit sensitivity.
