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 H-tilde GPD. These data will extend the Q{sup 2} range accessable by the existing CLAS data and the scheduled 6 GeV CLAS DVCS experiments to Q{sup 2} = 8 GeV{sup 2}.
