The LHCb silicon inner tracker

The inner part of the LHCb tracking system will be realised in a silicon microstrip technology. The experimental requirements suggest 20 cm long ladders and a readout pitch of around 240 μm. The complete LHCb Inner Tracker system will consist of nine stations with an overall silicon surface area of approximately 14 m2, depending on the final layout of the tracking system. A report about the current design of the silicon ladders and tracking stations of the Inner Tracker is given. First characterisations of prototype sensors and test beam results of ladders are presented.
