Preparation and Execution of the Electrical Quality Assurance Program On the LHC Superconducting Circuits During the Second Long Shutdown / Ludwin, Jaromir (CERN) ; Bednarek, Mateusz (CERN) ; Bednarski, Mikolaj (CERN ; Cracow, INP) ; Bielewski, Jaroslaw (CERN ; Cracow, INP) ; Bogdali, Pawel (CERN ; Cracow, INP) ; D'Angelo, Giorgio (CERN) ; Daniluk, Witold (CERN ; Cracow, INP) ; Dutkiewicz, Erazm Maria (CERN ; Cracow, INP) ; Grzadziel, Dominik (CERN ; Cracow, INP) ; Janik, Grzegorz (CERN ; Cracow, INP) et al.
The electrical quality assurance (ELQA) of the superconducting circuits of CERN’s Large Hadron Collider (LHC) during its second Long Shutdown (LS2) requires the execution of vast measurement campaigns. Each of 1658 electrical circuits as well as the instrumentation of each of the 1746 individual cryo-assemblies housing magnets, bus-bars and other components of the superconducting circuits, has to undergo a series of tests. [...]
