High Field Magnet Programme -- European Strategy Input
B. Auchmann, E. Todesco, A. Ballarino +6
In this submission, we describe research goals, implementation, and timelines of the High Field Magnet Programme, hosted by CERN. The programme pursues accelerator-magnet R&D with…
Transient Finite Element Simulation of Accelerator Magnets Using Thermal Thin Shell Approximation
Erik Schnaubelt, Andrea Vitrano, Mariusz Wozniak +3
Thermal transient responses of superconducting magnets can be simulated using the finite element (FE) method. Some accelerator magnets use cables whose electric insulation is signi…
Influence of Critical Current Distribution on Operation, Quench Detection and Protection of HTS Pancake Coils
Mariusz Wozniak, Erik Schnaubelt, Sina Atalay +5
High-temperature superconductor (HTS) coated conductors (CC) are often wound into pancake coils with electrical insulation in-between the turns. The copper terminals are used for c…
Energy Shift with Coupling (ESC): a new quench protection method
Emmanuele Ravaioli, Arjan Verweij, Mariusz Wozniak
Quench protection of full-size high-field accelerator magnets poses significant challenges. Maintaining the hot-spot temperature and peak voltage-to-ground within acceptable limits…
Challenges and Lessons Learned from fabrication, testing and analysis of eight MQXFA Low Beta Quadrupole magnets for HL-LHC
G. Ambrosio, K. Amm, M. Anerella +55
By the end of October 2022, the US HL-LHC Accelerator Upgrade Project (AUP) had completed fabrication of ten MQXFA magnets and tested eight of them. The MQXFA magnets are the low b…
MQXFA Final Design Report
Giorgio Ambrosio, Kathleen Amm, Mike Anerella +29
The MQXFA Quadrupole magnets will be installed in High Luminosity LHC to form the Q1 and Q3 inner triplet optical elements in front of the interaction points 1 (ATLAS) and 5 (CMS).…
Fast Failures in the LHC and the future High Luminosity LHC*
B. Lindstrom, P. Bélanger, L. Bortot +11
An energy of is stored in each of the two LHC proton beams for nominal beam parameters. This will be further increased to about in the future High…
STEAM: A Hierarchical Co-Simulation Framework for Superconducting Accelerator Magnet Circuits
Lorenzo Bortot, Bernhard Auchmann, Idoia Cortes Garcia +7
Simulating the transient effects occurring in superconducting accelerator magnet circuits requires including the mutual electro-thermo-dynamic interaction among the circuit element…
