Testrun results from prototype fiber detectors for high rate particle tracking

A fiber detector concept has been realized allowing to registrate particles within less than 100 nsec with a space point precision of about 0.1 mm at low occupancy. Three full size prototypes have been build by different producers and tested at a 3 GeV electron beam at DESY. After 3 m of light guides 8-10 photoelectrons were registrated by multichannel photomultipliers providing an efficiency of more than 99%. Using all available data a resolution of 0.086 mm was measured.Comment: 18 pages, 17 figure

High precision particle tracking with a fiber detector at the HERA ep-collider

A scintillating fiber detector is described, which shall be applied in a forward proton spectrometer supplementing the H1 detector. This detector has been tested with cosmic rays, and an average point resolution of 63#mu#m is obtained together with an average efficiency per double layer of 93%.

Beam tests of prototype fiber detectors for the H1 forward proton spectrometer

Different prototypes of fiber detectors with an internal trigger system were tested in a 5 GeV electron beam at DESY. A silicon microstrip telescope was used for an external reference measurement of the beam to study the spatial resolution of the fiber detectors. On average 75% of all crossing electron tracks could be reconstructed with a precision better than 150 #mu#m. These successful methodical investigations led to the installation of similar detectors in the proton beamline 81 m downstream of the central H1-detector at HERA as part of a forward proton spectrometer in spring 1994.
