论文摘要
到目前为止，无菌中微子的存在是中微子物理学中的一个悬而未决的问题。中微子振荡的方法提供了一种强大的工具来测试常见的3+1无菌中微子假设，即三种活跃的口味和一种无菌Falvor。该方法可以使用几种抗肿瘤来源。其中之一是$^{144} {\ rm ce}的众所周知的同位素链，$$^{144} {\ rm pr} $，在50-100 kCi左右的初始活动。它具有紧凑的尺寸，可以在检测器外部或内部安装。另一个是短寿命的同位素$ \ rm^8li $，可以在质子梁击中铍靶的核反应中产生。锂源仅具有较大尺寸，因此仅具有隔离器选项。提出的jin基水基液体闪烁体检测器将用作检测量。以上实验设置将使我们能够以90％C.L.涵盖振荡参数的最佳拟合值。同时，它对中微子-4结果的区域敏感。
The existence of sterile neutrino is an open question in neutrino physics up to now. The method of neutrino oscillometry provides a powerful tool to test the common 3+1 sterile neutrino hypothesis, i.e. three active flavors and one sterile falvor. There are several antineutrino sources can be used for this method. One of them is the well known isotope chain of $^{144}{\rm Ce}-$$^{144}{\rm Pr}$ with initial activity around 50-100 kCi. It has compact size and might be installed either outside or inside the detector. Another one is the short-lived isotope $\rm^8Li$, which can be produced in nuclear reaction of a proton beam hitting beryllium target. The Lithium source has only the out-of-detector option due to its large size. The proposed Jinping water-based liquid scintillator detector will be used as a detection volume. Above experimental setups will allow us to cover the current best fit values of oscillation parameters with 90% C.L. At the same time, it is sensitive to the region of Neutrino-4 result.
