摘要:

讨论了未来短基线实验中反中微子源的新概念。来源确保:结果表明,该装置具有以下优点:1)探测器体积约为立方米,每天计数率大于~(1 E +2 - 1 E +3),计数误差小于1%。拟议的来源是基于反应堆活性区附近7 Li的(n,γ)激活以及快速β衰变的8 Li同位素向远程中微子探测器的传输并返回闭环。建议的实验允许检测(电子反中微子,p)的相互作用,具有高精度,并针对搜索无菌中微子与无菌和活性中微子之间的平方质量差~1 eV 2。对(3+1)和(3+2)无菌中微子模型的模拟结果指出了在谱误差范围外寻找电子反中微子消失的空间区域。

英文摘要:

The new concept of antineutrino source for future short-baseline experiments is discussed. The source ensures: 1) well defined hard antineutrino flux; 2) the rate of counts more than ~(1E+2 - 1E+3) per day in the detector volume about cubic meter; 3) low level of count errors - < 1%. The proposed source is based on (n,gamma)-activation of 7Li near the reactor active zone and transport of the fast beta-decaying 8Li isotope toward a remote neutrino detector and back in the closed loop. The proposed experiment allows to detect (electron antineutrino, p)-interaction with high precision and directed to search of sterile neutrinos with squared-mass difference between sterile and active neutrinos ~1 eV2. The results of simulation for (3+1) and (3+2) sterile neutrino models indicate the space regions for search of electron antineutrino-disappearance outside the spectrum errors.
