Description
Recent advancements in Metastability Exchange Optical Pumping (MEOP) techniques have enabled the investigation of ³He nuclear spin polarization under high magnetic fields and varying gas pressures. At Jefferson Lab, we are employing MEOP of ³He nuclei at varying pressures using a fillable cell under magnetic fields ranging from 2 to 5 T. The current development focuses on creating a double-cell, cryogenic polarized ³He target for CLAS12 in Hall B at JLab, featuring a central solenoid that generates a magnetic field of 5T. We will present the polarization tests using current design for this target, and provide updates on progress so far in polarizing ³He using MEOP at JLab.
