  A fiber detector concept is suggested allowing to registrate particles within
less than 100 nsec with a space point precision of about 0.1 mm at low
occuppancy. The fibers should be radiation hard for 1 Mrad/year. Corresponding
prototypes have been build and tested at a 3 GeV electron beam at DESY.
Preliminary results of these tests indicate that the design goal for the
detector is reached.
