The x – y coupling effect, especially the tilt of the beam profiles, in the Super‐ALIS compact electron storage ring has been effectively eliminated. The main feature of this method is the suppression of the most harmful Fourier components of the skew‐quadrupole perturbation by using just one thin skew‐quadrupole magnet. Therefore, the method should be simple and effective for coupling suppression in compact storage rings that have little space for correction instruments.
