Nondestructive Testing and Quality Control of the LHC Main Interconnection Splices / Heck, S (CERN) ; Solfaroli, M (CERN) ; Andreassen, O (CERN) ; Thonet, P (CERN) ; Scheuerlein, C (CERN) ; Ballarino, A (CERN) ; Bertinelli, F (CERN) ; Bottura, L (CERN) ; Fessia, P (CERN) ; Tock, J (CERN)
The Large Hadron Collider (LHC) main interconnection splices consist of Rutherford-type cable splice and busbar stabilizer splices. Busbar stabilizer splices have been consolidated during the first long LHC shutdown by soldering additional Cu shunts. [...]

Electrical Resistance of the Solder Connections for the Consolidation of the LHC Main Interconnection Splices / Lutum, R (CERN) ; Heck, S (CERN) ; Scheuerlein, C (CERN)
For the consolidation of the LHC 13 kA main interconnection splices, shunts will be soldered onto each of the 10170 splices. The solder alloy selected for this purpose is Sn60Pb40. [...]

Production and Quality Assurance of Main Busbar Interconnection Splices during the LHC 2008-2009 Shutdown. / Bertinelli, F (CERN) ; Bottura, L (CERN) ; Dalin, J-M (CERN) ; Fessia, P (CERN) ; Flora, R H (Fermilab) ; Heck, S (CERN) ; Pfeffer, H (Fermilab) ; Prin, H (CERN) ; Scheuerlein, C (CERN) ; Thonet, P (CERN) et al.
The main busbar interconnection splices of the Large Hadron Collider are assembled by inductive soldering of the Rutherford type cables and the copper profiles of the stabilizer. Following the September 2008 incident, the assembly process and the quality assurance have been improved, with new measurement and diagnostics methods introduced. [...]

Quality Assurance of the 13-kA Superconducting Magnet Circuits Consolidation of the LHC at CERN / Principe, R (CERN) ; Gaasch, J B (CERN) ; Housiaux, O (CERN) ; Menu, S (CERN) ; Munawar, M (Islamabad, Pakistan AEC) ; Popescu, S (CERN) ; Savary, F (CERN)
The Large Hadron Collider (LHC) is designed to operate at a nominal energy of 14 TeV in the center of mass. Following the incident that occurred in 2008, LHC operated at intermediate energies ranging from 7 to 8 TeV to avoid any further risk of failure. [...]

Resistance of Splices in the LHC Main Superconducting Magnet Circuits at 1.9 K / Charifoulline, Zinour (CERN) ; Bednarek, Mateusz Jakub (CERN) ; Denz, Reiner (CERN) ; Le Naour, Sandrine (CERN) ; Scheuerlein, Christian (CERN) ; Siemko, Andrzej (CERN) ; Steckert, Jens (CERN) ; Tock, Jean-Philippe (CERN) ; Verweij, Arjan (CERN) ; Zerlauth, Markus (CERN)
The electrical interconnections between the LHC main magnets are made of soldered joints (splices) of two superconducting Rutherford cables, stabilized by a copper busbar. In 2009, a number of splices was found not properly stabilized and could have suffered a thermal runaway in case of quench at high current. [...]

Eddy current quality control of soldered current-carrying busbar splices of superconducting magnets / Kogan, L ; Nichipuruk, A ; Savary, F (CERN) ; Principe, R (CERN) ; Datskov, V ; Rozenfel'd, E ; Khudjakov, B
The eddy current technique associated with a U-shaped transducer is studied for the quality control of soldered joints between superconducting busbars ('splices'). Two other quality control techniques, based on X-rays and direct measurement of the electrical resistance, are also studied for comparison. [...]

The Electrical Resistance of Rutherford-Type Superconducting Cable Splices / Heck, C (CERN) ; Scheuerlein, Chr (CERN) ; Fleiter, J (CERN) ; Bottura, L (CERN)
The electrical resistance of Large Hadron Collider main busbar cable lap splices produced by soft soldering has been measured with two independent methods as a function of intercable contact area and for splices made of cables with various defects. For defect-free lap splices, the resistance increases from 0.3 to 10 nΩ (at 4.3 K in self-field) when reducing the cable overlap length from 120 to 3 mm, as expected assuming that the resistance is inversely proportional to the intercable contact area.
