The R3B (Reactions with Relativistic Radioactive Beams) experiment at GSI is a versatile setup that enables kinematically complete measurements. Tracking detectors are used at R3B to reconstruct the trajectories of charged particles as they pass through the magnetic field of the the GSI Large Acceptance Dipole (GLAD) magnet. This allows the magnetic rigidity of the particles to be determined.
This talk presents the design and performance of a position-sensitive scintillation-fiber detector that will be a part of the tracking system for heavy ions. The detector is constructed from ultra-thin scintillation fibers with a thickness of 200µm. Thin fibers are used to minimize the material budget in the particle trajectory and thus reduce straggling within the detector material. The fibers are read out with silicon photomultipliers, allowing the detector to operate in magnetic fields while maintaining high detection efficiency.
