The HERMES Recoil Silicon Detector — •Andreas Mussgiller for the HERMES collaboration — II. Physikalisches Institut, Universität Erlangen-Nürnberg, 91058 Erlangen

As the innermost component of the HERMES recoil detector, the silicon detector provides momentum and position measurement of recoiling protons in elastic and exclusive positron proton scattering. It covers proton recoil momenta between 135 MeV/c and 500 MeV/c. The detector consists of 16 large-area (10·10 cm²) double-sided silicon strip detectors with a strip pitch of 758 µm arranged in two layers around the target cell inside the HERA beam vacuum.
The detector is now fully operational. Production data taking with the recoil silicon detector started in late September 2006 and will continue until the final HERA shutdown in July 2007.
The project is supported by BMBF, Projekt Nr. 06 ER 125 I und 06 ER 243.
