Aluminum Stabilized Conductor for the Fermilab D0 Solenoid

摘要

The aluminum stabilized conductor for the superconducting 2T solenoid for the DO detector at Fermilab has been designed, fabricated, and tested. A Rutherford cable of Cu:NbTi multifilamentary superconducting strands was clad with 4N8 aluminum using the 'conform' continuous extrusion technique. The quality control measurements made during the production of the conductor are discussed and measurements of the degradation in Ic caused by the cabling and cladding are presented. The characteristics of the soft solder joints used in the coil are described.
