The cyclotron of the IPNAS-CEA laboratory of the University of Liège (Belgium) has built a new high-energy, high-resolution beam line based on the use of a pair of 90° bending magnets showing a energy resolution of

comparable to that of electrostatic IBA installations. In the 6–20
MeV energy range the contribution of non-Rutherford events to scattering spectra became important and are not very well known. In order to improve our knowledge in that field, a new vacuum chamber especially dedicated to differential cross-section measurements has been constructed. First results obtained with the new set-up are presented.
