Description
The calibration of the ATLAS MDT chambers will be performed at remote sites,
called Remote Calibration Centers. Each center will process the calibration
data for the assigned part of the detector and send the results back to CERN
for general use in the reconstruction and analysis within 24h from the
calibration data taking.
In this work we present the data extraction mechanism, the data transfer
mechanism and the structure of the remote calibration centers. A particular
focus will be given to the processing techniques in the calibration centers,
the failover mechanisms and the process control system, called Local
Calibration Data Splitter (LCDS).
The full architecture has been successfully used during the cosmic data taking
runs and has been proven to be powerful, robust and stable enough to cope with
the real data taking. The preliminary results on the system performance,
obtained during the cosmic data taking runs in 2008, will be discussed and the
plans for the real data taking period will be presented.
