DOIAbstract
Back-streaming neutrons through the incoming proton channel at the spallation target station of China Spallation Neutron Source (CSNS) has been exploited as a white neutron beam line (so-called Back- n), and a number of spectrometers for nuclear data measurements have been planned. With a thick tungsten target and modest moderation by the cooling water through the target slices, the neutron beam is very intense which is in the order of 5.0x10(6) n/cm(2)/s at 80m from the target and has an excellent energy spectrum spanning from 1 eV to 100MeV. In addition, the time structure of the primary proton beam under different accelerator operation modes is fully applicable for time-of-flight measurements. Altogether, it makes the CSNS Back-n very mu...
