Test and performance of the scintillating fibre tracker for the HERMES recoil detector — •Roberto Perez, Michael Düren, Matthias Hartig, Matthias Hoek, Tibor Keri, Shaojun Lu, Lukas Rubacek, Björn Seitz, and Hasko Stenzel — II. Physikalisches Institut, Uni Giessen, 35392 Giessen

The HERMES recoil detector will operate a scintillating fibre tracker to identify and track protons for momenta up to 1400 MeV/c.

Scintillating fibers are an ideal tool to combine energy and position measurements for charged particles in an intermediate momentum range. They offer a high granularity while keeping the mechanical construction and material density at a minimum. Modules build from Kuraray SCSF–78 fibres of 1 mm diameter were tested at a secondary beam consisting of pions and protons at various momenta from 300 MeV/c to 900 MeV/c. Their particle identification and spatial resolution properties were tested. Data from these tests will be presented together with data using a 5 GeV/c electron beam for precise position and resolution studies of the final detector.
