Zusammenfassung: | We describe a detector system which can uniquely identify heavy projectile fragments produced in nucleus-nucleus reactions in the few GeV/nucleon energy region. The system consists of a superconducting dipole magnet with (1) a drift chamber for tracking, (2) a Cherenkov hodoscope for charge measurements, (3) a Cherenkov hodoscope for velocity measurements, and (4) a multiplicity array to measure the number of participant protons. We have achieved a charge resolution of
