Description
In 2004, a full slice of the ATLAS detector was tested for 6 months in the H8
experimental area of the CERN SPS, in the so-called Combined Test Beam, with beams of
muons, pions, electrons and photons in the range 1 to 350 GeV. Approximately 90
million events were collected, corresponding to a data volume of 4.5 terabytes. The
importance of this exercise was two-fold: for the first time the whole ATLAS software
suite was used on fully combined real data. Besides, a novel production
infrastructure was employed for the reconstruction of the real data as well as for a
massive production of simulated events.
The talk will be focused on the Combined Test Beam production system. The system is
comprised of two components for two distinct tasks: reconstruction of real data and
production of simulated samples. Large scale real data reconstruction was performed
twice in 2005 at CERN. In both cases a sizable sample of about 400 good runs, for a
total of about 25 million events, were processed. Also in 2005, the Monte Carlo
production was for the first time performed on the grid, with the simulation of about
4 Million events. Reprocessing of real data, as well as Monte Carlo production on the
grid, are already planned for the year 2006.
