We report on a new measurement of 14N(p,gamma)15O for the ground state capture transition at E_p = 360, 380 and 400 keV, using the 400 kV LUNA accelerator. The true coincidence summing effect the major source of error in the ground state capture determination has been significantly reduced by using a Clover-type gamma detector.
