Ezio Todesco,Bernhard Auchmann,Marta Bajko,Luca Bottura,Oliver Brüning,Gijs de Rijk,Paolo Fessia,Per Espen Hagen,Sandrine Le Naour,Michele Modena,Juan Carlos Perez,Lucio Rossi,R. Schmidt,Andrzej Siemko,J. P. Tock,Davide Tommasini,Arjan Verweij,Gerard Willering +17 more
TL;DR: In this article, an analysis of the quench performance of the LHC dipole magnets is reported, including individual reception tests and the 2008 and 2015 commissioning campaigns, to better understand the above-mentioned anomaly and give an outlook for future operation and possible increase of the operational field.
Journal ArticleDOI

TL;DR: A first overview of the most common electrical faults and their frequency of occurrence in the first years of operation at the LHC is provided to perform a statistical analysis that can provide reference values for future productions of similar dimensions and nature.
Journal ArticleDOI
Performance improvement of a measurement station for superconducting cable test.
TL;DR: A fully digital system, improving measurements flexibility, integrator drift, and current control of superconducting transformers for cable test, is proposed, based on a high-performance integration of Rogowski coil signal and a flexible direct control of the current into the secondary windings.
The Second LHC Long Shutdown (LS2) for the Superconducting Magnets
J. P. Tock,M. Bednarek,Luca Bottura,Efstathios Karentzos,Sandrine Le Naour,Florian Meuter,Mirko Pojer,Christian Scheuerlein,Ezio Todesco,Davide Tommasini,Lisette Van Den Boogaard,Gerard Willering +11 more
TL;DR: In this paper, the design of reinforced electrical insulation of the dipole cold diodes and the associated project organization are presented, including the validation tests, especially at cryogenics temperature.
