Production and qualification of the 60-kA, aluminum stabilized conductor for the ATLAS B0 coil / L. Rossi, M. Sorbi, G. Volpini, D. Pedrini, C. Berriaud, I.L. Horvath. - In: IEEE TRANSACTIONS ON APPLIED SUPERCONDUCTIVITY. - ISSN 1051-8223. - 9:2(1999 Jun), pp. 209-212. [10.1109/77.783273]
Abstract:
For the toroidal ATLAS magnet system some 90
km of aluminum stabilized conductor are required. The
conductor is a Rutherford cable, coextruded with very pure
aluminum . The main characteristics of the conductor are: 1) a
very large critical current, 60 kA at 5 T and 4.2 K; 2) RRR of the
stabilizing aluminum of at least 1000 on the finished conductor;
3) a good bonding between the Rutherford cable and the
stabilizer: a shear stress of 20 MPa is required; 4) 1750 m of unit
length. To assure a good quality of the conductor all along the
production and to minimize the risk of rejection of such
expensive units, a strict quality assurance was established. The
paper describes the results of the R&D phase to set all
parameters to produce the first two unit lengths necessary for the
winding of the BO coil (a 9 m long model.coi1 of the ATLAS
Barrel Toroid). It also describes the control system based on
continuous ultrasonic inspection, able to. provide images of the
cable inside the aluminum that is used to evaluate on line the
quality of aluminum to cable bonding.
