Performance of long ladders for the LHCb silicon tracker

The LHCb Silicon Tracker uses detector ladders with readout strips with an effective length of up to 36 cm. Kapton interconnect cables of up to 54 cm in length are employed in between silicon sensors and front-end readout hybrids. Fast front-end readout electronics with a shaping time of around 25 ns are employed to avoid pile-up of events from consecutive LHC bunch crossings. An extensive measurement program as well as simulations has been carried out to study the expected noise performance of these detectors.
