本文重新审视了基于储存环(“β束”)中的增强放射性离子的中微子工厂的精确测量和发现潜力。与过去的设计相比,假设离子γ因子为1000,基线L=130 km,我们强调将离子提升到更高的γ并按比例增加基线的优点。特别地,我们考虑了“中γ”情景(γ = 500,L = 730 km)和“高γ”情景(γ = 2000,L = 3000 km)。随着平均束能量线性增长的统计数据的增加、利用信号的能量依赖性的能力以及在这个较长基线处的相当大的物质效应都非常显著地增加了这种机器的发现潜力。
The precision measurement and discovery potential of a neutrino factory based on boosted radioactive ions in a storage ring (“β-beam”) is re-examined. In contrast with past designs, which assume ion γ factors of ∼100 and baselines of L=130 km, we emphasize the advantages of boosting the ions to higher γ and increasing the baseline proportionally. In particular, we consider a “medium-γ” scenario (γ∼500, L∼730 km) and a “high-γ” scenario (γ∼2000, L∼3000 km). The increase in statistics, which grow linearly with the average beam energy, the ability to exploit the energy dependence of the signal and the sizable matter effects at this longer baseline all increase the discovery potential of such a machine very significantly.
