Mechanical stress analysis during a quench in CLIQ protected 16 T dipole magnets designed for the future circular collider / Zhao, Junjie (Lanzhou U.) ; Prioli, Marco (CERN) ; Stenvall, Antti (Tampere U. of Tech.) ; Salmi, Tiina (Tampere U. of Tech.) ; Gao, Yuanwen (Lanzhou U.) ; Caiffi, Barbara (INFN, Genoa) ; Lorin, Clement (Saclay) ; Marinozzi, Vittorio (Milan Bicocca U. ; INFN, Milan) ; Farinon, Stefania (INFN, Genoa) ; Sorbi, Massimo (Milan Bicocca U. ; INFN, Milan)
Protecting the magnets in case of a quench is a challenge for the 16 T superconducting dipole magnets presently designed for the 100 TeV: Future Circular Collider (FCC). These magnets are driven to the foreseen technological limits in terms of critical current, mechanical strength and quench protection. [...]

The 16 T dipole development program for FCC and HE-LHC / Schoerling, Daniel (CERN) ; Arbelaez, Diego (LBNL, Berkeley) ; Auchmann, Bernhard (PSI, Villigen) ; Bajko, Marta (CERN) ; Ballarino, Amalia (CERN) ; Barzi, Emanuela (Fermilab) ; Bellomo, Giovanni (INFN, Milan) ; Benedikt, Michael (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Bordini, Bernardo (CERN) et al.
A future circular collider (FCC) with a center-of-mass energy of 100 TeV and a circumference of around 100 km, or an energy upgrade of the LHC (HE-LHC) to 27 TeV require bending magnets providing 16 T in a 50-mm aperture. Several development programs for these magnets, based on Nb$_3$Sn technology, are being pursued in Europe and in the U.S. [...]

Quench protection of the 16 T Nb3Sn dipole magnets designed for the Future Circular Collider / Salmi, Tiina (Tampere U. of Tech.) ; Prioli, Marco (CERN) ; Stenvall, Antti (Tampere U. of Tech.) ; Verweij, Arjan P (CERN)
Three different 16 T dipole magnet options for the Future Circular Collider (FCC) have been designed within the H2020 EuroCirCol collaboration, namely a cosθ-, a block-, and a common-coil -type of magnet. All magnets were designed using the same constraints related to magnetic field, cable parameters, mechanics, and quench protection. [...]

How to Computationally Determine the Maximum Stable Operation Current of an HTS Magnet / Ruuskanen, Janne (Tampere U. of Tech.) ; Stenvall, Antti (Tampere U. of Tech.) ; Lahtinen, Valtteri (Tampere U. of Tech.) ; van Nugteren, Jeroen (CERN) ; Kirby, Glyn (CERN) ; Murtomäki, Jaakko (Tampere U. of Tech.)
The short-sample critical current is only an indicative property for the maximum current a magnet can be continuously operated with. This was especially visible in the experiments of one of the world's first Roebel-cable-based high temperature superconductors dipole magnet prototype built and tested at CERN in 2017 where the thermal runaway developed very slowly in many cases.

3-D Mechanical Modeling of 20 T HTS Clover Leaf End Coils—Good Practices and Lessons Learned / Murtomäki, Jaakko Samuel (CERN ; Tampere U. of Tech.) ; van Nugteren, Jeroen (CERN) ; Stenvall, Antti (Tampere U. of Tech.) ; Kirby, Glyn (CERN) ; Rossi, Lucio (CERN)
Very high electromagnetic forces are generated in the superconducting coils of high field accelerator magnets. The cables, which are used to wind the coils, can withstand limited pressure levels and strains generated during the powering without degradation. [...]

Modelling thermodynamics in a high-temperature superconducting dipole magnet: an inverse problem based approach / Ruuskanen, J (Tampere U. of Tech.) ; Stenvall, A (Tampere U. of Tech.) ; Lahtinen, V (Tampere U. of Tech.) ; van Nugteren, J (CERN) ; Kirby, G (CERN) ; Murtomäki, J (Tampere U. of Tech.)
The use of practical high temperature superconductors (HTS), REBCO tapes especially, in magnet applications has become possible thanks to the increasing interest of manufacturers. One difficulty has been the nonlinear material properties that are challenging to measure and model. [...]

10 kA Joints for HTS Roebel Cables / Murtomaki, Jaakko Samuel (CERN) ; Kirby, Glyn (CERN) ; van Nugteren, Jeroen (CERN) ; Contat, Pierre-Antoine (CERN) ; Sacristan-de-Frutos, Oscar (CERN) ; Fleiter, Jerome (CERN) ; Pincot, Francois-Olivier (CERN) ; de Rijk, Gijs (CERN) ; Rossi, Lucio (CERN) ; Ruuskanen, Janne (Tampere U. of Tech.) et al.
Future high temperature superconductor (HTS) high field magnets using multitape HTS cables need 10-kA low-resistance connections. The connections are needed between the poles of the magnets and at the terminals in a wide-operating temperature range, from 1.9-85 K. [...]

Powering of an HTS dipole insert-magnet operated standalone in helium gas between 5 and 85 K / Van Nugteren, J (CERN) ; Kirby, G (CERN) ; Bajas, H (CERN) ; Bajko, M (CERN) ; Ballarino, A (CERN) ; Bottura, L (CERN) ; Chiuchiolo, A (CERN) ; Contat, P-A (CERN) ; Dhallé, M (Twente U., Enschede) ; Durante, M (Saclay) et al.
This paper describes the standalone magnet cold testing of the high temperature superconducting (HTS) magnet Feather-M2.1-2. This magnet was constructed within the European funded FP7-EUCARD2 collaboration to test a Roebel type HTS cable, and is one of the first high temperature superconducting dipole magnets in the world.

ICED—Inductively Coupled Energy Dissipater for Future High-Field Accelerator Magnets / Murtomäki, Jaakko Samuel (CERN) ; van Nugteren, Jeroen (CERN) ; Kirby, Glyn (CERN) ; de Rijk, Gijs (CERN) ; Rossi, Lucio (CERN) ; Stenvall, Antti (Tampere U. of Tech.)
Future high-field accelerator magnets, like the ones foreseen in the design study of the FCC project and for the EuCARD2 “Future Magnets” program, operate with magnetic fields in the range of 16-20 T. For such magnets the energy density is higher than in the accelerator magnets at present in operation, posing a challenge for the quench protection. [...]
