Calibration and production of praxial sensors for the ATLAS muon spectrometer
Ph. Schune
The future LHC experiment, ATLAS [1], features a muon spectrometer in which the alignment system must control the spatial position of the muon chambers with an accuracy of 30 microns and 200 micro-radian in a range of displacements of 5mm and 5mrad. The alignment system described in this paper, called praxial, fulfils these requirements. The paper reviews the relative and absolute calibration procedures and the production of the 1005 praxial sensors needed in ATLAS.
