The optics of the exotic beam line at LNL

The EXOTIC collaboration is installing a facility for the in flight production of exotic ion beams at INFN Legnaro National Laboratories (LNL). The RIBs are produced in inverse kinematics mode via intense TANDEM/ALPI primary beams hitting a light gas target (H, d, He-3, He-4). The results of the optics calculation for F-17 produced by the O-17(p,n)F-17 reaction are presented. Special care has been adopted to stop, at several points perpendicular to the beam direction, the contaminants due to the primary beam.
