| 英文摘要 | A white neutron beam line using back-streaming neutrons from the spallation target is under construction at china spallation neutron source (csns). different spectrometers, to be installed in the so-called back-n beam line for nuclear data measurements, are also being developed in phases. the physical design of the beam line is carried out with the help of a complicated collimation system and a sophisticated neutron dump, taking the overview of the neutron beam characteristics into account. this includes energy spectrum, flux and time structure, the optimizations of neutron beam spots and in-hall background. the wide neutron energy range of 1 ev-100 mev is excellent for supporting different applications, especially nuclear data measurements. at endstation#2, which is about 80 m away from the target, the main properties of the beam line include neutron flux of 106 n/cm(2)/s, time resolution of a few per mille over nearly the entire energy range, and in-hall background of about 0.01/cm(2)/s for both neutron and gamma. with its first commission in late 2017, back-n will not only be the first high-performance white neutron source in china, but also one of the best white neutron sources in the world. |
