Inductive method to measure very small joint resistances of superconducting wires / Herzog, R ; Hagedorn, Dietrich
In the Large Hadron Collider (LHC), which is currently being developed at CERN, about 50,000 connections of superconducting wire will be necessary to implement all circuits for powering 6000 corrector magnets with a maximum current of 600 A. To minimise the generation of ohmic heat in the cryogenic system, it is necessary to reduce the contact resistance of these connections as much as possible. [...]

Influence of strand surface condition on interstrand contact resistance and coupling loss in NbTi-wound Rutherford cables / Sumption, M D ; Collings, E W ; Scanlan, R M ; Nijhuis, A ; ten Kate, H H J ; Kim, S W ; Wake, M ; Shintomi, T
Presented in this work are the results of directly measured and AC- loss-derived interstrand contact resistance (ICR) measurements performed magnetically or resistively on bare-Cu and coated-strand pairs, calorimetrically on $9 11-strand Rutherford cables wound with strands that had been coated with various metallic and insulating layers, and calorimetrically and magnetically on 28-strand Rutherford cables (LHC-type) wound with bare-Cu-, Ni-, and $9 stabrite-plated strands. Comparisons are made of the effects of various conditions of heat treatment, HT (time and temperature), and pressure (applied during HT and then either maintained or re-applied during measurement).

Development of high performance Nb-Ti(Fe) multifilamentary superconductor for the LHC insertion quadrupoles / Lee, P J ; Fischer, C M ; Gabr-Rayan, W ; Larbalestier, D C ; Naus, M T ; Squitieri, A A ; Starch, W L ; Barzi, E ; Limon, P J ; Sabbi, G L et al.
A development program was initiated in order to develop strand with improved current density at 10.5 T and 1.9 K over existing SSCL designs. The two successful strand designs reported on here both utilized high Fe content Nb-47 wt%Ti alloys to improve the critical current density at high field by 7%. [...]

Magnetization measurements on LHC superconducting strands / Le Naour, S ; Oberli, L R ; Wolf, R ; Puzniak, R ; Szewczyk, A ; Wisniewski, A ; Fikis, H ; Foitl, M ; Kirchmayr, H
When using superconducting magnets in particle accelerators like the LHC, persistent currents in the superconductor often determine the field quality at injection, where the magnetic field is low. This paper describes magnetization measurements made on LHC cable strands at the Technical University of Vienna and the Institute of Physics of the Polish Academy of Sciences in collaboration with CERN [...]

Development of high performance multifilamentary Nb-Ti-Ta superconductor for LHC insertion quadrupoles / Lee, P J ; Fischer, C M ; Larbalestier, D C ; Naus, M T ; Squitieri, A A ; Starch, W L ; Werner, J ; Limon, P J ; Sabbi, G L ; Zlobin, A V et al.
A preliminary investigation of a new Nb-Ti-Ta (39 wt.Nb, 44 wt.Ti, 17 wt.Ta) alloy has been investigated as a possible material for application at 1.9 K and 10.5 T in the insertion quadrupoles of LHC, 1550 A/mm/sup 2/, the highest $9 yet reported critical current density at 10.5 T (1.9 K), was achieved in a monofilament of this material. The initial multifilamentary production strand produced a lower 10.5 T (1.9 K) critical current density of 1370 A/mm/sup 2/. [...]

Performance of the LHC Final Design, Full-Scale Superconducting Dipole Prototypes / Bottura, L ; Pugnat, P ; Siemko, A ; Vlogaert, J ; Wyss, C
Within the LHC magnet program, a series of six, final design, full-scale superconducting dipole prototypes are presently being built in industry and tested at CERN. The main features of these magnets are: two-in-one structure, 56 mm aperture, six-block two layer coils wound from 15.1 mm wide graded NbTi cables, and all-polyimide insulation. [...]

Variations in the characteristics of the superconducting wire used for the ISR superconducting high-luminosity insertion / Billan, J ; Rinn, J ; Wolf, R
A total of 30000 meters of NbTi solid multifilamentary superconductor, I/sub c/ approximately 2500 A at 6 T, was tested. For each stretch of wire received, measurements were made to check if the wire met the specifications. [...]

Powder-in-tube (PIT) Nb$_{3}$Sn conductors for high-field magnets / Lindenhovius, J L H ; Hornsveld, E M ; den Ouden, A ; Wessel, W A J ; ten Kate, H H J
New Nb/sub 3/Sn conductors, based on the powder-in-tube (PIT) process, have been developed for application in accelerator magnets and high-field solenoids. For application in accelerator magnets, SMI has developed a binary 504 filament PIT conductor by optimizing the manufacturing process and adjustment of the conductor lay-out. [...]

Superconductive technologies for the Large Hadron collider at CERN / Rossi, L
The Large Hadron Collider (LHC) project is the largest plant based on superconductivity and cryogenics: 27 km of tunnel filled with superconducting magnets and other equipment that will be kept at 1.9 K. The dipole magnets have to generate a minimum magnetic field of 8.3 T to allow collisions of proton beams at an energy of 14 TeV in the centre of mass. [...]
