摘要:

不育中微子的存在是中微子物理学中的一个悬而未决的问题。中微子能量测量方法为检验常见的3+1不育中微子假说,即三种活性味和一种不育味提供了强有力的工具。有几种反中微子源可以用于这种方法。其中之一是众所周知的$^{144}{\rm Ce}-$ $^{144}{\rm Pr}$的同位素链,其初始活性约为50-100 kCi。它具有紧凑的尺寸,可以安装在探测器的外部或内部。另一种是短寿命同位素$\rm^8Li$,它可以在质子束撞击铍靶的核反应中产生。由于锂源的尺寸较大,因此只有探测器外选项。拟采用锦屏水基液体闪烁体探测器作为探测体。上述实验设置将使我们能够覆盖振荡参数的当前最佳拟合值,90% C. L。同时,它对中微子-4结果的区域敏感。

英文摘要:

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.
