Abstract :
In the Atlas muon spectrometer (ATLAS Technical Proposal, CERN/LHCC/94-43, 15 December 1994, ATLAS Muon Spectrometer Technical Design Report, CERN/LHCC/97-22, 31 May 1997 and http://atlasinfo.cern.ch:80/Atlas/Welcome.html) the alignment system should control the spatial position of the muon chambers with an accuracy of 30 μm and 200 μrad for a range of ±5 mm and ±10 mrad. The alignment device described in this paper, called Praxial, fulfills these requirements.
