The ATLAS central solenoid magnet is being constructed to provide a magneti
c field of 2 Tesla in the central tracking part of the ATLAS detector. As a
key technology for the solenoid coil as thin as possible, high-strength al
uminum stabilized superconductor has been developed with achieving a yield
strength of > 100 MPa at 4.2K. This paper describes the status of the desig
n and development of the solenoid magnet.
