Abstract:
As the first high-performance white neutron source in China, the CSNS Back-n was constructed at China Spallation Neutron Source (CSNS). It is among the world best white neutron sources in overall performance, with the wide neutron energy coverage from meV to hundreds of MeV, the time resolution for time-of-flight measurements within 1% for almost the whole energy range, and the leading neutron flux at a flight distance longer than 50 m. Since March 2018, a number of experiments including nuclear data measurement, detector calibration, neutron irradiation and neutron imaging were conducted at Back-n with high scientific productivity, and the experimental results and data meet the requirements of the users. Back-n provides a very powerful platform for fundamental research and applications of different fields in China. In this paper, the performance of the neutron source, experimental spectrometers for nuclear data measurements in operation or planned and major research or applications are reviewed in general.
