我们提出了几个测量CsI[Na]闪烁响应3-60 keV能量核反冲的COHERENT合作使用标记中子弹性散射实验和端点技术进行的结果。早期的结果，用于估计相干弹性中微子-核散射（CEvNS）的事件率的第一次观察这个过程中实现的相干在Spinning中子源（SNS），已被重新评估。我们讨论了已确定的系统效应的校正，并更新了相应的不确定性值。估计了更新结果对CEvNS未来精度测试的影响。我们仔细检查可能影响每个测量的潜在系统效应。特别是，我们确认的H11934-200滨松光电倍增管（PMT）用于本研究中提出的测量是线性的相关信号标度区域的响应。
We present results of several measurements of CsI[Na] scintillation response to 3–60 keV energy nuclear recoils performed by the COHERENT collaboration using tagged neutron elastic scattering experiments and an endpoint technique. Earlier results, used to estimate the coherent elastic neutrino-nucleus scattering (CEvNS) event rate for the first observation of this process achieved by COHERENT at the Spallation Neutron Source (SNS), have been reassessed. We discuss corrections for the identified systematic effects and update the respective uncertainty values. The impact of updated results on future precision tests of CEvNS is estimated. We scrutinize potential systematic effects that could affect each measurement. In particular we confirm the response of the H11934-200 Hamamatsu photomultiplier tube (PMT) used for the measurements presented in this study to be linear in the relevant signal scale region.
