The superconducting magnet system for the ATLAS detector at CERN

The ATLAS superconducting magnet system for the ATLAS detector in the LHC at CERN comprises a barrel toroid (BT), two end cap toroids and a central solenoid, with overall dimensions of 20-m diameter by 26-m length. Though this magnet system is used for a particle detector, its size, geometrical arrangement and coil technology is comparable to what is usual for fusion machines. The manufacturing has started in the industry and integration of the magnets will start in the year 2002. Assembly in the cavern will start at the end of the year 2003, starting with BT installation. In this paper, the magnet system is presented as well as the common infrastructure and services.
