本文简要介绍了中国科学院近代物理研究所ADS相关核数据实验研究进展.基于兰州重离子加速器冷却储存环(HIRFL-CSR)搭建了核数据实验测量终端,建立中子飞行时间谱仪、轻带电粒子谱仪和水浴活化等实验装置,并开展了一系列ADS关键材料的核数据实验研究,包括400 MeV/u 16O离子束轰击钨靶和铅靶的实验,296 MeV氘束轰击铅靶和厚铍靶的实验,以及250 MeV质子轰击厚钨靶和厚铅靶的水浴活化实验.实验测量主要研究了ADS散裂反应相关的中子产额、能谱、双微分截面等数据.另一方面,基于中国原子能科学研究院核数据重点实验室的中子积分实验装置,开展了ADS靶堆耦合相关材料镓、石墨、碳化硅、钨、铀等样品的积分实验,检验了ENDF/B-VII.1,CENDL-3.1,JENDL-4.0,JEFF-3.2及TENDL-2015等数据库中相关材料的中子评价数据.

Recent progress in nuclear data measurement for ADS

Recent progress in nuclear data measurement for ADS at IMP is reviewed briefly. Based on the Cooler Storage Ring of Heavy Ion Research Facility in Lanzhou(HIRFL-CSR), the nuclear data terminal was established, which mainly includes neutron time-of-flight spectrometer, light charged particles spectrometer and water-bath neutron activation setup. A number of experiments have been conducted in the nuclear data terminal. The experiments of 400 MeV/u 16O bombarded on tungsten target and lead target, 296 MeV deutron bombarded on lead target and thick beryllium target, 250 MeV protons incident on a thick grain-made tungsten target and a thick solid lead target using the water-bath neutron activation method were performed in the nuclear data terminal. The nuclear data of neutron yields, energy or time spectrum, double differential cross section and so on have been investigated. On the other hand, based on the neutronics integral experimental setup at China Institute of Atomic Energy, benchmarking of evaluated nuclear data libraries was performed on ADS relevant materials gallium, graphite, silicon carbine, tungsten, uranium samples and so on. ENDF/B-VII.1, CENDL-3.1, JENDL-4.0, JEFF-3.2 and TENDL-2015 libraries were validated.
