1.9 K test facility for the reception of the superconducting cables for the LHC
TL;DR: In this article, a new test facility for measuring the electrical properties of the LHC superconducting cables was constructed at CERN, with the main features being: independently cooled background magnet, test currents up to 32 kA, temperature between 1.8 and 4.5 K, long measurement length of 60 cm, field perpendicular or parallel to the cable face, measurement of the current distribution between the strands.

TL;DR: In this article, six contracts have been placed with industrial companies for the production of 1200 tons of the superconducting (SC) cables needed for the main dipoles and quadrupoles of the Large Hadron Collider (LHC).
Journal ArticleDOI
DC measurement of electrical contacts between strands in superconducting cables for the LHC main magnets
TL;DR: In this article, the effect of the cable treatment has on the contact resistance was discussed under various conditions and the properties of resistive barriers, the DC method used for the resistance measurement on the cable, and sample preparation were described.
Journal ArticleDOI
Critical Current Density in Superconducting $rm Nb-Ti$ Strands in the 100 mT to 11 T Applied Field Range
TL;DR: In this article, the critical current density of LHC-type Nb-Ti strands of 0.82 and 0.48 mm diameter was measured by means of critical current and magnetization measurements at both 4.2 K and 1.9 K and for a broad magnetic field range (up to 11 T).
