First Use of a Polarized $^3$He Neutron Spin Filter on the Back-n White Neutron Source of CSNS

Autor: Zhang, Mofan, Yang, Zhou, Zhang, Junpei, Huang, Chuyi, Wang, Tianhao, Chen, Yonghao, Fan, Ruirui, Snow, W. Michael

Polarized eV neutrons can address interesting scientific questions in nuclear physics, particle physics, and astrophysics/cosmology. We present the first experiment to polarize the neutrons on the Back-n beamline at the Chinese Spallation Neutron Sou

Differential cross-section measurements for neutron-induced $\alpha$ production reactions on carbon across neutron energy range of 6.2 to 76 MeV

Angle-differential cross sections for neutron-induced $\alpha$ production in carbon were determined at thirty discrete neutron energy levels ranging from 6.2 to 76 MeV at the Back-n white neutron source of the China Spallation Neutron Source. Utilizi
