摘要：

在RIKEN Nishina中心（日本）安装了一个新的探测系统，以研究非常丰中子核的衰变特性。该装置由三个主要部分组成：慢化中子计数器，对放射性离子的注入和衰变敏感的探测系统，以及伽马射线探测器。我们在这里描述的设置，调试实验和一些选定的结果表明其性能的半衰期和β-缓发中子发射概率的测量。在数据分析中遵循的方法进行了详细说明。特别强调的是放在事故中子本底的校正。

英文摘要：

A new detection system has been installed at the RIKEN Nishina Center (Japan) to investigate decay properties of very neutron-rich nuclei. The setup consists of three main parts: a moderated neutron counter, a detection system sensitive to the implantation and decay of radioactive ions, and gamma-ray detectors. We describe here the setup, the commissioning experiment and some selected results demonstrating its performance for the measurement of half-lives and beta-delayed neutron emission probabilities. The methodology followed in the analysis of the data is described in detail. Particular emphasis is placed on the correction of the accidental neutron background.
