论文摘要
在这项工作中进行的研究是对距离橡树岭国家实验室中的散布中微子相互作用（NSI）的非标准中微子相互作用（NSI）的敏感性。假定的原型由10 kg未凝固的CSI闪烁晶体直接与在77 K处操作的SIPM阵列直接耦合。与相干CSI（NA）检测器相比，假定原型的光产量更高。进行了一项圆柱形未凝聚的CSI晶体，直接在约77 K处耦合到光电层管，以验证光屈服假设。 [13，60] Kevee在[13，60] kevee中实现了$ 33.5 \ pm 0.7 $光电电子（PE/KEVEE）的产量，该kevee的收率比一些早期研究更接近NSI搜索的相关能量区域。
Investigated in this work are sensitivities to non-standard neutrino interactions (NSI) of a prototype detector placed about 20 meters away from the Spallation Neutron Source at the Oak Ridge National Laboratory in two years of data taking. The presumed prototype consists of 10 kg undoped CsI scintillation crystals directly coupled with SiPM arrays operated at 77 K. Compared to the COHERENT CsI(Na) detector, a much higher light yield is assumed for the prototype. An experiment with a cylindrical undoped CsI crystal coupled directly to a photomultiplier tube at about 77 K was conducted to verify the light yield assumption. A yield of $33.5 \pm 0.7$ photoelectrons per keV electron-equivalent (PE/keVee) was achieved in [13, 60] keVee, which is much closer to the relevant energy region for the NSI search than some of the early studies.
