Description
The ATLAS experiment of the LHC is now taking its first data by
collecting cosmic ray events. The full reconstruction chain including
all sub-systems (inner detector, calorimeters and muon spectrometer)
is being commissioned with this kind of data for the first time.
Specific adaptations to deal with particles not coming from the
interaction point and not synchronized with the readout clock were
needed. Data decoders and the infrastructure to deal with conditions
data as those coming from the data acquisition configuration, detector
control system, calibration and alignment corrections were developed
and validated as well.
Detailed analysis are being performed in order to provide ATLAS with
its first alignment and calibration constants and to study the
combined muon performance. Combined monitoring tools and event
displays have also been developed to ensure the good data quality.
A simulation of cosmic events according to the different detector and
trigger setups has also been provided to verify it gives a good
description of the data.
