For time being the moments quantifying the amount of inter-plane coupling, as <xy'> for instance, have been accessible to measurements just for very special cases of ions at energies below 200 keV/u using pepperpots. This talk presents successful measurements of all inter-plane coupling moments at 1 to 11 MeV/u. From first principles the used methods are applicable at all ion energies. The first campaign applied skewed quadrupoles in combination with a regular slit/grid emittance measurement device. The second campaign used a rotatable slit/grid device in combination with regular quadrupoles.
