We describe a planned experiment to measure the longitudinal target‐spin asymmetry in the DVCS process using CLAS12 detector. While the beam‐spin asymmetry is more sensitive to H GPD, measurements of the target‐spin asymmetry allow us to access the H̃ GPD. These data will extend the Q2 range accessable by the existing CLAS data and the scheduled 6 GeV CLAS DVCS experiments to Q2 = 8 GeV2.
