橡树岭国家实验室 (ORNL) 提出了几项建造类似于中子散裂源 (SNS) 设施的提案。这些也是中能中微子的丰富来源。我们使用 SNS 的参数来计算来自停止π介子的中微子和来自撞击高 Z 目标的质子的 μ 子的光谱、通量和时间结构。我们证明了中微子-核截面测量的广泛计划的可行性，这对于可以在此类设施中进行的弱相互作用核物理和核天体物理非常重要。
There are several proposals to build facilities similar to the neutron spallation source (SNS) under construction at the Oak Ridge National Laboratory (ORNL). These are also prolific sources of intermediate energy neutrinos. We have used the parameters of the SNS to compute the spectra, flux and time structure of neutrinos from stopped-pions and muons from protons impinging on a high-Z target. We demonstrate the feasibility of a broad programme of measurements of neutrino–nucleus cross-sections, important in weak interaction nuclear physics and nuclear astrophysics that could be carried out at such facilities.
