在液氮温度下操作的纯CsI的明亮闪烁使这种材料成为一种有前途的暗物质和中微子探测器。我们提出了第一次测量其淬火因子的核反冲。我们的发现表明，在室温下，它与钠掺杂的CsI没有区别。在108-165 K的温度范围内研究了其他性质，如光产额，余辉，电子和核反冲的闪烁衰减特性以及能量比例，证实了这种介质在稀有事件搜索方面的巨大潜力。
The bright scintillation of pure CsI operated at liquid-nitrogen temperature makes of this material a promising dark matter and neutrino detector. We present the first measurement of its quenching factor for nuclear recoils. Our findings indicate it is indistinguishable from that for sodium-doped CsI at room temperature. Additional properties such as light yield, afterglow, scintillation decay properties for electron and nuclear recoils, and energy proportionality are studied over the 108-165 K temperature range, confirming the vast potential of this medium for rare-event searches.
