“…The alignment of the Inner Detector components has been done with charged-hadron beams with beam momenta between 5 and 180 GeV/c [19]. The RMS for the residuals was 10 µm for the Pixel modules and 25 µm for the SCT modules.…”

In 2004 at the ATLAS (A Toroidal LHC ApparatuS) combined test beam, one slice of the ATLAS barrel detector (including an Inner Detector set-up and the Liquid Argon calorimeter) was exposed to particles from the H8 SPS beam line at CERN. It was the first occasion to test the combined electron performance of ATLAS. This paper presents results obtained for the momentum measurement p with the Inner Detector and for the performance of the electron measurement with the LAr calorimeter (energy E linearity and resolution) in the presence of a magnetic field in the Inner Detector for momenta ranging from 20 GeV/c to 100 GeV/c. Furthermore the particle identification capabilities of the Transition Radiation Tracker, Bremsstrahlungs-recovery algorithms relying on the LAr calorimeter and results obtained for the E/p ratio and a way how to extract scale parameters will be discussed.

“…All the alignment algorithms were used to align the ID setup with this data [11]. Different sets of beams of e+/e-, µ+/µ-, γ and pions with energies varying from 2 to 180 GeV and with/without magnetic field runs gave abundant statistics (O(10 5 ) tracks per module and per energy run).…”

The ATLAS Experiment is one of the four detectors located at the Large Hadron Collider at CERN in Geneva, Switzerland. It is a multi-purpose detector that will study high-energy particle collisions and which main aim is the Higgs boson discovery. The reconstruction of charged particle tracks and their decay vertices is performed by a sohisticated tracking system based on silicon sensors and drift tubes called Inner Detector. In order not to degenerate the track measurements, the position of the silicon detector elements has to be known to a precision better than about 10 µm. This precision can be achieved thanks to track-based alignment algorithms combined with measurements from hardware based alignment techniques. The proposed alignment algorithms for the ATLAS Inner Detector and their implementation into the common ATLAS software framework are presented as well as the alignment strategy. Moreover, alignment results from testbeams, MonteCarlo simulations and real cosmic rays data are shown and discussed. Finally this note will also emphasize the importance of global distortions, so-called weak modes. 17th International Workshop on Vertex detectors

The Semiconductor Tracker (SCT) is one of the three sub-systems of the ATLAS internal tracker. Its complete installation and sign-off took about 18 months and was finished at the beginning of 2008. Since then, the SCT has been run successfully taking data in combined mode with the other ATLAS sub-systems. The major problems related with cooling failures and the mortality of off-detector opto-chips have been solved. As in summer 2009, more than 99% of the main detector components are fully working. Detailed calibration procedures have been applied to optimize the detector performance. An initial alignment has been achieved using cosmic ray real data. Some results in terms of tracking performance and Lorentz angle measurements are also shown.
