| contents | 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 Source (CSNS) using an in-situ NSF using spin-exchange optical pumping (SEOP) of 3He. A 3He polarization of 68%$\pm$0.7% for this in-situ NSF was measured through neutron transmission method at Back-n.This is high enough to enable new experiments on the Back-n beamline.
