Performance of the First LHC Pre-series Superconducting Dipoles / Bottura, L ; Leroy, D ; Modena, M ; Pojer, M ; Pugnat, P ; Rossi, L ; Sanfilippo, S ; Siemko, A ; Vlogaert, J ; Walckiers, L et al.
Within the LHC magnet program, a preseries production of final design, full-scale superconducting dipoles has presently started in industry and magnets are being 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. [...]

Persistent and Coupling Current Effects in the LHC Superconducting Dipoles / Amet, S ; Bottura, L ; Granata, V ; Le Naour, S ; Mishra, R K ; Oberli, L R (CERN) ; Richter, D ; Sanfilippo, S ; Verweij, A P ; Walckiers, L et al.
One of the main issues for the operation of the LHC accelerator at CERN is the field errors generated by persistent and coupling currents in the main dipoles at injection conditions, i.e., 0.54 T dipole field. For this reason we are conducting systematic magnetic field measurements to quantify the above effects and compare them to the expected values from measurement on strands and cables. [...]

Test Results of a Variant-Design LHC Twin-Aperture Dipole Magnet / CERN-Japan LHC Construction Collaboration
Since 1989, KEK and CERN carried out jointly an experimental program in the frame of the R&D; work for the LHC main dipole. The mechanical structure of this design is based on a separate coil/collar and "horizontally split iron" concept. [...]

A Method to Determine the Flexural Rigidity of the Main Dipole for the Large Hadron Collider / La China, M ; Cavallari, Giorgio ; Ferracin, P ; García-Pérez, J ; Todesco, Ezio ; Scandale, Walter
The Large Hadron Collider (LHC) superconducting dipole cold mass is a cylindrical structure 15 m long, made of a shrinking cylinder which contains iron laminations and collared coils. This structure, weighing about 28 ton is horizontally bent by 5 mrad. [...]

The LHC Main Dipoles and Quadrupoles toward Series Production / Rossi, L
The Large Hadron Collider (LHC) is under construction at CERN. Most of its 27 km underground tunnel will be filled with superconducting magnets, mainly 15 m long dipoles and 3.3 m long quadrupoles. [...]

Analytical Calculation of Current Distribution in Multistrand Superconducting Cables / Bottura, L ; Breschi, M ; Fabbri, M G
In recent years the problem of current distribution in multistrand superconducting cables has received increasing attention for large scale superconductivity applications due to its effect on the stability of fusion magnets and the field quality of accelerator magnets. A modelling approach based on distributed parameters has revealed to be very effective in dealing with long cables made of some tens or hundreds of strands. [...]
