Polarized Semi-Inclusive DIS measurements at Jefferson Lab

Longitudinally polarized electrons with energies of 4.2 and 5.7 GeV and longitudinally polarized proton and deuteron targets were used to measure the double spin asymmetries in semi-inclusive deep-inelastic scattering. Scattered electrons and electro-produced pions where detected in the CEBAF Large Acceptance Spectrometer at Jefferson Lab. The kinematic range covered is: $0.31$ GeV$^2$, $0.12
