Acceleration and relative position of atoms during deceleration and trap loading. a Acceleration, and (b) relative longitudinal position in the z dimension with respect to the final position of the trap minimum, of H atoms in the |n,k〉=|30,25〉 state for which the time-dependence of the deceleration potentials was optimised. The origin of the horizontal axis is the activation time of the deceleration potentials
