摘要

欧洲核子研究中心的n_TOF设施是专门为研究中子诱导核反应而设计的研究基础设施。脉冲白中子束被送到三个实验区，其中两个在不同的基线上应用飞行时间技术，另一个非常接近中子源进行激活研究。高强度和高中子能量分辨率使n_TOF成为一种独特的设备。n_TOF物理项目的一个主要组成部分是致力于测量核天体物理学中的关键中子诱导反应，这些反应与恒星中的核合成、大爆炸原始核合成以及宇宙年代学有关。报告了在n_TOF设施获得的相关结果的审查，以及正在准备的具有挑战性的新测量的细节。

The Nuclear Astrophysics Program at the CERN n_TOF Facility: Results and Perspectives

The CERN n_TOF facility is a research infrastructure specifically designed for studying neutron-induced nuclear reactions. Pulsed white neutron beams are delivered toward three experimental areas, two of them at different baselines to apply the time-of-flight technique, and another one very close to the neutron source for activation studies. High intensity and high neutron energy resolution make n_TOF a unique facility. A major component of the physics program at n_TOF is dedicated to the measurement of key neutron induced reactions for nuclear astrophysics, relevant to nucleosynthesis in stars, the Big Bang primordial nucleosynthesis as well as Cosmochronology. A review of the relevant results obtained at the n_TOF facility is reported, together with details of challenging new measurements in preparation.
