THE DESIGN OF SILICON MINISTRIP DETECTORS FOR THE DELPHI VERY FORWARDTRACKER

The DELPHI Very Forward Tracker will extend the tracking capabilities of the DELPHI microvertex detector in the forward region. It consists of 4 cones of pixel and silicon strip detectors with large strip pitch . The silicon ministrip detector is optimized for high track reconstru ction efficiency and momentum resolution at a minimum number of electr onic channels. The properties of silicon strip detectors with large st rip pitch in terms of charge collection and spatial resolution were in vestigated.
