Secondary beams (6Li,7Be,8B) were obtained by the separation of fragmentation products of a15N ion beam (50 MeV/A) impinging on a Be target using the COMBAS spectrometer. The secondary products were detected by a telescope consisting of five Si-detectors (dE) and a stop CsI(Tl) detector. The telescope allowed us to achieve unambiguous particle identification of fragments originating from incident secondary beams as well as their reaction products resulting from interaction with the Sidetectors, chosen as a secondary target. This way, break-up reactions of6Li,7Be and8B have been studied in this experiment, in particular the longitudinal momentum distributions of7Be fragments in the break-up of8B on a Si have been measured at 30 MeV/A.
