Reduced Order Hysteretic Magnetization Model for Composite Superconductors / Dular, Julien (CERN) ; Verweij, Arjan (CERN) ; Wozniak, Mariusz (CERN)
In this paper, we propose the Reduced Order Hysteretic Magnetization (ROHM) model to describe the magnetization and instantaneous power loss of composite superconductors subject to time-varying magnetic fields. [...]

Coupled Axial and Transverse Currents Method for Finite Element Modelling of Periodic Superconductors / Dular, Julien (CERN) ; Magnus, Fredrik (CERN ; Norwegian U. Sci. Tech.) ; Schnaubelt, Erik (CERN ; Darmstadt, Tech. Hochsch.) ; Verweij, Arjan (CERN) ; Wozniak, Mariusz (CERN)
In this paper, we propose the Coupled Axial and Transverse currents (I) (CATI) method, as an efficient and accurate finite element approach for modelling the electric and magnetic behavior of periodic composite superconducting conductors. The method consists of a pair of two-dimensional models coupled via circuit equations to account for the conductor geometrical periodicity. [...]

An open-source 3D FE quench simulation tool for no-insulation HTS pancake coils / Atalay, Sina (CERN ; Bogazici U.) ; Schnaubelt, Erik (CERN ; Darmstadt, Tech. Hochsch.) ; Wozniak, Mariusz (CERN) ; Dular, Julien (CERN) ; Zachou, Georgia (CERN ; Natl. Tech. U., Athens) ; Schöps, Sebastian (Darmstadt, Tech. Hochsch.) ; Verweij, Arjan (CERN)
A new module, Pancake3D, of the open-source Finite Element Quench Simulator (FiQuS) has been developed in order to perform transient simulations of no-insulation (NI) high-temperature superconducting (HTS) pancake coils in 3-dimensions. FiQuS/Pancake3D can perform magnetodynamic or coupled magneto-thermal simulations. [...]

Quench Protection of Stacks of No-Insulation HTS Pancake Coils by Capacitor Discharge / Mulder, Tim (CERN) ; Wozniak, Mariusz (CERN) ; Verweij, Arjan (CERN)
No-Insulation (NI) technology for HTS coils has been around for a decade and is a proven method to protect small pancake coils in case of a quench. Without turn-to-turn insulation, excess current can bypass a sudden resistive part, thereby possibly preventing damaging the conductor locally. [...]

Interpretable Anomaly Detection in the LHC Main Dipole Circuits With Nonnegative Matrix Factorization / Obermair, Christoph (CERN ; Graz, Tech. U.) ; Apollonio, Andrea (CERN) ; Charifoulline, Zinour (CERN) ; Felsberger, Lukas (CERN) ; Janitschke, Marvin (CERN ; U. Rostock) ; Pernkopf, Franz (Graz, Tech. U.) ; Ravaioli, Emmanuele (CERN) ; Verweij, Arjan (CERN) ; Wollmann, Daniel (CERN) ; Wozniak, Mariusz (CERN)
CERN's Large Hadron Collider (LHC), with its eight superconducting main dipole circuits, has been in operation for over a decade. During this time, relevant operational parameters of the circuits, including circuit current, voltages across magnets and their coils, and current to ground, have been recorded. [...]

Quench Co-Simulation of Canted Cos-Theta Magnets / Wozniak, Mariusz (CERN) ; Schnaubelt, Erik (CERN ; Darmstadt, Tech. U.) ; Dular, Julien (CERN) ; Ravaioli, Emmanuele (CERN) ; Verweij, Arjan (CERN)
Canted Cos-Theta (CCT) magnets can use conducting formers in which eddy currents are induced during current change. This is relevant during magnet ramping or discharging after a quench, particularly when using energy extraction. [...]

Magneto-Thermal Thin Shell Approximation for 3D Finite Element Analysis of No-Insulation Coils / Schnaubelt, Erik (CERN ; Darmstadt, Tech. U.) ; Atalay, Sina (CERN ; Bogazici U.) ; Wozniak, Mariusz (CERN) ; Dular, Julien (CERN) ; Geuzaine, Christophe (Liege U.) ; Vanderheyden, Benoît (Liege U.) ; Marsic, Nicolas (Darmstadt, Tech. U.) ; Verweij, Arjan (CERN) ; Schöps, Sebastian (Darmstadt, Tech. U.)
For finite element (FE) analysis of no-insulation (NI) high-temperature superconducting (HTS) pancake coils, the high aspect ratio of the turn-to-turn contact layer (T2TCL) leads to meshing difficulties which result in either poor quality mesh elements resulting in a decrease of the solution accuracy or a high number of degrees of freedom. We proposed to mitigate this issue by collapsing the T2TCL volume into a surface and using a so-called thin shell approximation (TSA). [...]

LHC Triplet Task Force Report / Arduini, Gianluigi (CERN) ; Bradu, Benjamin (CERN) ; Brodzinski, Krzysztof (CERN) ; Bruce, Roderik (CERN) ; Cerutti, Francesco (CERN) ; Ciccotelli, Alessia (University of Manchester (GB)) ; Deferne, Guy (CERN) ; Fartoukh, Stephane (CERN) ; Fessia, Paolo (CERN) ; Garion, Cedric (CERN) et al.
The excellent performance of the Large Hadron Collider (LHC) and the extension of Run 3 by one year have led to a significant increase of the expected integrated luminosity by the end of its operation and before the start of the High Luminosity LHC (HL-LHC), exceeding the design LHC integrated luminosity of 300 fb−1 for which the final focus region has been designed.
