Description
One of the central goals of nuclear and particle physics is to understand the internal dynamics of nucleons in terms of quarks and gluons, the fundamental degrees of freedom of quantum chromodynamics. The semi-inclusive deep inelastic scattering (SIDIS) is a golden channel to access the three-dimensional imaging and the spin structure of the nucleon. For neutron studies, a spin polarized $^3$He target has been widely used for decades as an effective polarized neutron target. Recently, a program of spin-dependent electron scattering from polarized $^3$He has been proposed at the CLAS12 spectrometer at Jefferson Lab with a novel polarized $^3$He target being developed. This talk will present the details of the proposed experiment and discuss the new opportunities on the SIDIS measurement on $^3$He at CLAS12.
