摘要
拟议的长基线中微子观测站（LBNO）最初由约20千吨的液氩双相时间投影室和磁化铁量热器组成，将安装在Pyhäsalmi矿，距离CERN 2300公里。常规中微子束由SPS加速器加速的400 GeV质子产生，提供700 kW功率。长基线为研究中微子味振荡在其第一和第二振荡极大值处的L/E行为，以及区分δ_CP和物质效应提供了独特机会。在本文中，我们展示了如果来自Protvino IHEP加速器复合体的中微子束（距离1160公里，功率为450 kW）指向相同的远探测器，这一全面的物理案例如何得到进一步增强和补充。我们表明，来自CERN和Protvino的两个独立亚兆瓦常规中微子和反中微子束在不同基线上的耦合，将允许在轻子扇区以至少3σ的置信水平测量CP破坏，对于50%的δ_CP真值，使用20千吨探测器。对于70千吨的远探测器，运行10年后，该组合对75%的δ_CP真值提供3σ灵敏度。运行两个独立的、每个功率低于1 MW的中微子束，比长期运行一个新的高能多兆瓦设施更符合当前技术水平，后者存在若干技术挑战，并且可能需要学习曲线。
