We present below the magnetic forces measured on IN22 with the 15T symmetric split-pair coil magnet 158OXHV26. Two configurations have been considered: at 2.662Å-1 and 5.812Å-1. In each case, the A4 shaft has been scanned to look for the angle leading to the maximum force.

For working at nominal field, the distance between the lead blocks of the primary spectrometer and the surface of the cryomagnet (on the incident beam axis and at the height of the beam) must be 1375 mm for the 15T and 1175 mm for the 12T.
