Abstract
In order to try to settle the question of the origin of the EMC effect, experiments will be performed to study polarized EMC effects at Hall B at Thomas Jefferson National Accelerator Facility (JLab).
They will use longitudinally polarized 11 GeV electron beams and longitudinally polarized $^7$LiD and NH$_3$ targets with CLAS12 detectors.
JLab target and collaborating groups (Hall B group, engineering and accelerator divisions) are preparing an irradiation beam line, designing and constructing irradiation and DNP (Dynamic Nuclear Polarization) polarizing cryostats.
