Polarizing ³He via metastable exchange optical pumping at varied magnetic fields.*

Nuclear-spin polarized ³He serves as a powerful tool to observe neutron spin structure,  where it can be used as an effective polarized neutron target. Recent advancements in high-magnetic-field metastability exchange optical pumping of ³He, aimed at medical imaging and creating a polarized ³He ion source for the EIC, has opened avenues for utilizing polarized ³He targets in high magnetic fields, including Jefferson Lab's CLAS12 spectrometer. We are employing metastability exchange optical pumping of ³He nuclei at varying pressures using a fillable cell under magnetic fields ranging from 2 to 5 T. This work presents an initiative to develop an innovative polarized ³He target to be located in the central solenoid of the CLAS12 detector at Jefferson Lab. The progress, status, and plans for the realization of the target will be presented.
