An active target with plastic scintillating fibers has been constructed. This active target serves as a production target of hyperons, as well as a scattering target, and works as a 4/spl pi/-detector for charged particles. This system is designed for measurements of hyperon-proton scattering for hyperon momenta of several hundred MeV/c. A spectrometer system for the incident beam and outgoing particles of the hyperon production reaction is linked with this target-detector in order to provide triggers for the imaging device of this detector system. As a control of this detector, the decay constant of the /spl Sigma//sup -/ hyperon has been evaluated.
