Abstract

The ATLAS central solenoid magnet is being constructed to provide a magnetic field of 2 Tesla in the central tracking part of the ATLAS detector at the LHC. Since the solenoid coil is placed in front of the liquid-argon electromagnetic calorimeter, the solenoid coil must be as thin land transparent) as possible. The high-strength and high-RRR aluminum-stabilized superconductor is a key technology for the solenoid to be thinnest while keeping itsstability. This has been developed with an alloy of 0.1wt% nickel additionto 5N pure aluminum and with the subsequent mechanical cold working of 21%in area reduction. A yield strength of 110MPa at 4.2K has been realized with keeping a residual resistivity ratio (RRR) of 590, after a heat treatment corresponding to the coil curing at 130 degrees C for 15 hrs. This paper describes the optimization of the fabrication process and characteristics of the developed conductor.
