Abstract-For the main dipole and quadrupole magnets of the LHC, CERN has ordered from industry about 7000 km of superconducting Nb-Ti Rutherford type cables, delivered between 1999 and 2005. The strands of these cables are produced by six different companies, and cabled on five different machines. In the framework of the US contribution to the LHC, BNL has been testing and analyzing the electrical properties of samples of these cables. The main purpose of these tests was to qualify the critical current of the entire cable production in the frame of the quality assurance program implemented by CERN to assure the overall strand and cable performances.In total more than 2100 cable samples have been evaluated at 4.3 K in terms of critical current C , n-value and the residual resistance ratio, RRR. This paper will present an overview of the results, and show the correlations of the critical current and n-value between virgin strands, extracted strands, and cables.Also described are correlations of C measured at BNL and those made at the FRESCA facility in CERN. Furthermore a few trends and anomalies of the cable production that were detected from testing cables are highlighted.

“…Such magnet will serve as a technology test bed for LHC luminosity upgrade [2]- [4]. It can be used also to upgrade an existing superconducting cable test facility at CERN, presently limited to a 10-T background field [5]. The NED activity is also meant to complement the vigorous efforts on accelerator magnet technology carried out in the USA within the framework of the US-LHC Accelerator Research Program (LARP) [6] or as part independently-funded base programs at Lawrence Berkeley National Laboratory [7] and Fermi National Accelerator Laboratory [8].…”

“…The record for a Nb-Ti dipole belongs to the 88 mm aperture dipole used in the cable test station at CERN [70], which has a two-layer cosθ design with 16.7 mm cable width, and a short sample field of 10.15 T. It reached 10.09 T after a short training and is routinely used to measure the cable critical current at 10 T. Similar performances were obtained by the D19 model in LBL, having a maximum quench field of 10.06 T with a strongly graded two-layer coil of 2*12 mm thickness [71]. A 10% increase to get an 11 T short sample limit would require doubling the coil width with respect to the LHC dipoles (see Fig.…”

Superconducting magnets have played a key role in advancing the energy reach of proton synchrotrons and enabling them to play a major role in defining the Standard Model. The problems encountered and solved at the Tevatron are described and used as an introduction to the many challenges posed by the use of this technology. The LHC is being prepared to answer the many questions beyond the Standard Model and in itself is at the cutting edge of technology. A description of its magnets and their properties is given to illustrate the advances that have been made in the use of superconducting magnets over the past 30 years.
