摘要
利用内部 Ar 源对双相氙时间投影室 XENON1T 进行了低能电子反冲刻度。该刻度源具有 35 天的半衰期，并提供 2.82 keV 和 0.27 keV 两条单能谱线。在 2.82 keV 处测得的光子产额和电子产额分别为 (32.30.3) photons/keV 和 (40.60.5) electrons/keV，与其他测量及 NEST 预测一致。0.27 keV 处的电子产额亦被测得，为 (68.0) electrons/keV。Ar 刻度证实探测器在接近探测阈值的能量区域中被充分理解，2.82 keV 谱线被重建于 (2.830.02) keV，这进一步验证了用于解释 XENON1T 先前报道的低能电子反冲超出所采用的模型。刻度后利用低温蒸馏高效去除氩气的能力证明，Ar 可被视为多吨级氙探测器的常规刻度源。
