New Measurement Techniques Used for the Electrical Quality Assurance of HL-LHC Superconducting Magnets / Ludwin, Jaromir (Cracow, INP ; CERN) ; Bednarek, Mateusz (CERN) ; Rosa, Tiago Catalo Da (CERN ; Unlisted, PT)
In preparation of the Large Hadron Collider (LHC) upgrade to High Luminosity LHC (HL-LHC), a number of new Nb3Sn magnets, including short model and prototype magnets, had to be electrically qualified. The process included a number of well-established Electrical Quality Assurance (ELQA) tests, such as electrical continuity checks of the magnet instrumentation, High-Voltage (HV) insulation tests of the magnet and quench heater circuits, and impedance measurements. [...]

Characterization of the Copper Resistance in the LHC Main Dipole Bypass Diode Leads / Bednarski, Mikolaj (Cracow, INP) ; Ludwin, Jaromir (Cracow, INP) ; Wojas, Damian (Cracow, INP) ; Bednarek, Mateusz (CERN) ; D’Angelo, Giorgio (CERN)
A fundamental component of the quench protection system of the large hadron collider (LHC) superconducting dipole magnets are bypass diodes. During a quench, the high current powering the magnet coil is redirected through the parallel diode. [...]

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.

Upgrade of the Arc Interconnection Verification System for the Large Hadron Collider / Bednarski, Mikolaj (Cracow, INP) ; Jurkiewicz, Piotr (Cracow, INP) ; Ludwin, Jaromir (Cracow, INP) ; Wojas, Damian (Cracow, INP) ; Bednarek, Mateusz (CERN) ; D'Angelo, Giorgio (CERN)
This article presents the design and construction of a new version of an automated, highly efficient system for validation of connections between superconducting magnets in the Large Hadron Collider at CERN, Genève, Switzerland.The design of the new version is based on the existing comprehensive system for electrical measurements and is its integral part. The new system is dedicated to perform multi channel resistance measurements and is to be used during machine assembly and magnets replacement..
