Abstract

In 2002, an innovative neutron time-of-flight facility started operation at CERN: n_TOF. The main characteristics that make the new facility unique are the high instantaneous neutron flux, high resolution and wide energy range. Combined with state-of-the-art detectors and data acquisition system, these features have allowed to collect high accuracy neutron cross-section data on a variety of isotopes, many of which radioactive, of interest for Nuclear Astrophysics and for applications to advanced reactor technologies. A review of the most important results on capture and fission reactions obtained so far at n_TOF is presented, together with plans for new measurements related to nuclear industry.

摘要

2002年，欧洲核子研究中心（CERN）一个创新的中子飞行时间装置开始运行：n_TOF。使这个新装置独一无二的主要特性是高瞬时中子通量、高分辨率和宽能量范围。结合最先进的探测器和数据采集系统，这些特性使得能够收集关于各种同位素的高精度中子截面数据，其中许多是放射性同位素，这些数据对于核天体物理学以及先进反应堆技术的应用都很重要。本文介绍了到目前为止在n_TOF上获得的关于俘获和裂变反应的最重要结果，以及与核工业相关的新测量计划。
