keyword=polarization loss during rotation of the field
Rotate the main holding field of polarized 3He target to longitudinal pumping configuration. Did the NMR measurement of the target polarization, see figure below, before turn on the longitudinal pumping laser. It seems there is about 3% (absolute) polarization loss.
