Description
T Cornelissen on behalf of the ATLAS inner detector software group
Several million cosmic tracks were recorded during the combined ATLAS runs in Autumn of 2008. Using these cosmic ray events as well as first beam events, the software infrastructure of the inner detector of the ATLAS experiment (pixels and microstrips silicon detectors as well as straw tubes withadditional transition radiation detection) is being commissioned.
The full software chain has been set up in order to reconstruct and
analyse this kind of events. Final detector decoders have been
developed, different pattern recognition algorithms and track fitters
have been validated as well as the various calibration
methods. The infrastructure to deal with conditions data coming from
the data acquisition, detector control system and calibration runs
has been put in place, allowing also to apply alignment and calibration
constants.
The software has also been essential to monitor the detector
performance during data taking. Detector efficiencies, noise
occupancies and resolutions are being studied in detail as well as the performance of the track reconstruction itself.
