对太阳CNO聚变循环中中微子的首次测量将有助于解决当前太阳金属丰度问题。这些低能量中微子的检测需要一个低阈值的检测器，而在感兴趣的区域的放射性背景的歧视显着增强通过定向灵敏度。这种组合可以在水基液体闪烁体靶中实现，其提供超过标准水切伦科夫探测器的增强的能量分辨率。我们研究了这样的探测器的灵敏度CNO中微子在各种探测器和背景的情况下，并得出这样的探测器成功地测量CNO中微子通量的要求的结论。设计用来测量CNO中微子的探测器也可以实现对PEP中微子的百分之几的测量。
A first measurement of neutrinos from the CNO fusion cycle in the Sun would allow a resolution to the current solar metallicity problem. Detection of these low-energy neutrinos requires a low-threshold detector, while discrimination from radioactive backgrounds in the region of interest is significantly enhanced via directional sensitivity. This combination can be achieved in a water-based liquid scintillator target, which offers enhanced energy resolution beyond a standard water Cherenkov detector. We study the sensitivity of such a detector to CNO neutrinos under various detector and background scenarios, and draw conclusions about the requirements for such a detector to successfully measure the CNO neutrino flux. A detector designed to measure CNO neutrinos could also achieve a few-percent measurement of pep neutrinos.
