Description

With a total area of more than 200 square meters and about 16000 silicon detectors the Tracker of the CMS experiment will be the largest silicon detector ever built. The CMS silicon Tracker will detect charged tracks and will play a determinant role in lepton reconstruction and heavy flavour quark tagging. A general overview of the Tracker data handling software, which allows the detector to be configured, calibrated, monitored and its data to be analysed by means of distributed computing resources and databases is given. Results of the Tracker performance as obtained in the various setups where the Tracker is being commissioned are also presented. A first functional version of the Tracker data handling software was tested in the CMS Magnet Test Cosmic Challenge (MTCC). At the MTCC a small fraction of all the CMS subdetectors was operated in the 4T solenoid of the experiment. Cosmic rays were triggered by the muon detectors and all subdetectors were readout with the global data acquisition system. The MTCC Tracker setup represented about 1% of the final system. A much larger fraction of the Tracker is currently being readout at the Tracker Integration Facility (TIF) where large parts of the full Silicon Strip Detector are already integrated. The data handling software in use at the TIF is close to final.

Summary

A general overview of the Tracker data handling software, which allows the detector
to be configured, calibrated, monitored and its data to be analysed by means of
distributed computing resources and databases is given. Results of the Tracker
performance as obtained in the various setups where the Tracker is being commissioned
are also presented.
