Magnets

Central Solenoid

The central ATLAS solenoid has a length of 5.3 m with a bore of 2.4 m. The conductor is a composite that consists of a flat superconducting cable located in the center of an aluminum stabaliser with rectangular cross-section. It is designed to provide a field of 2 T in the central tracking volume with a peak magnetic field of 2.6 T. To reduce the material build-up the solenoid shares the cryostat with the liquid argon calorimeter.

Toroid Magnet

The ATLAS Toroid Magnet system consists of eight Barrel coils housed in separate cryostats and two End-Cap cryostats housing eight coils each. The End-Cap coils systems are rotated by 22.5° with respect to the Barrel Toroids in order to provide radial overlap and to optimise the bending power in the interface regions of both coil systems.
