摘要:

双相液体氙(LXe)探测器引领了对粒子暗物质的直接搜索。了解Lion中核反冲的信号产生过程对于解释基于Lion的暗物质搜索至关重要。到目前为止,只有两个实验同时测量了不同电场下的光和电荷产额,这两个实验都没有试图评估导致光和电荷产生的过程。在这封信中,从液体氙的中子校准与同时光和电荷检测的结果,从3-74千电子伏的能量,在电场为0.19,0.49,和1.02千伏/厘米。没有观察到显着的字段依赖性的产量。

英文摘要:

Dual-phase liquid xenon (LXe) detectors lead the direct search for particle dark matter. Understanding the signal production process of nuclear recoils in LXe is essential for the interpretation of LXe based dark matter searches. Up to now, only two experiments have simultaneously measured both the light and charge yield at different electric fields, neither of which attempted to evaluate the processes leading to light and charge production. In this letter, results from a neutron calibration of liquid xenon with simultaneous light and charge detection are presented for energies from 3-74 keV, at electric fields of 0.19, 0.49, and 1.02 kV/cm. No significant field dependence of the yields is observed.
