4. In-situ optical pumping for polarizing 3He neutron spin filters at the China Spallation Neutron Source.

Zhang, Junpei, Huang, Chuyi, Qin, Zecong, Ye, Fan, Amir, Syed Mohd, Salman, Ahmed, Dong, Yuchen, Tian, Long, Buck, Zachary Nortis, Kreuzpaintner, Wolfgang, Musgrave, Matthew, Qi, Xin, Wang, Tianhao, and Tong, Xin

Abstract

In this paper, we present the performance of a recently developed in-situ spin-exchange optically pumped3 He-neutron spin filter system at the China Spallation Neutron Source (CSNS). The system achieved a 3He polarization of over 74% at the beamline BL-20. Analysis of neutron transmission experiment results reveals a neutron polarization of > 90% and an average transmission of 27% for 2.2 Å neutrons, which were maintained for a duration of 120 h of beam time. To the best of our knowledge, this is the first in-situ hyperpolarized 3He system incorporated on a neutron beamline in China. This technology is expected to provide stable, wide-angle, and highly polarized neutrons at the CSNS for materials research and fundamental neutron physics. [ABSTRACT FROM AUTHOR]
