Superconducting magnets are the enabling technology for NMR spectroscopy. This research technique is behind the recent advancements in physics, biology, chemistry, material sciences and physiology. Bruker BioSpin is a technological leader in the field of NMR systems. With the growing importance of high-resolution NMR applications at highest magnetic fields, Bruker envisages the development of superconducting magnets above 23.5 T. Since many years, UNIGE and Bruker Biospin have been working together within several collaboration frameworks, the goal being the development of both low- and high-Tc technical superconductors with enhanced properties in high magnetic fields.
CERN and UNIGE have a common interest in the field of applied superconductivity. A key objective of CERN is to exploit the Large Hadron Collider at its utmost performance. In particular, it is foreseen to build 11T-dipoles and 12T-quadrupoles based on Nb3Sn wires in view of the High Luminosity upgrade. The task of the collaboration between CERN and UNIGE consists in an extensive research program focused on development and characterization of new, advanced superconducting wires and cables required to achieve these high magnetic fields.
The goals of ARIES are the development of novel concepts and the improvement of the performance and sustainability of particle accelerators, transferring the benefits and applications of accelerator technology to both science and society. To address these challenges, ARIES brings together a consortium of 42 beneficiaries from 18 countries: accelerator laboratories, technology institutes, universities and industrial partners. The project is coordinated by CERN and co-funded under the European Commission’s Horizon 2020 Research and Innovation programme. Building on the technical success of EuCARD-2, our task is to drive the development of a new generation of higher performance/lower cost REBCO (Rare earth – Barium – Copper Oxide) coated conductors, in order to bridge the gap between technical performance and readiness for application.
EuroCirCol is a conceptual design study for a post-LHC research infrastructure based on an energy-frontier 100 TeV/100 km circular hadron collider. It was selected for funding within the Horizon 2020 Research and Innovation Framework Programme. The Consortium is composed of 16 universities, research organisations and laboratories from seven countries of the European Union, Switzerland and Japan, under the lead of CERN. Innovative designs for future accelerator magnets to achieve high-quality fields up to 16 T are amongst the main challenges that are being addressed. The Group of Applied Superconductivity has the role to define the electromechanical limits of the superconducting wires envisaged for use in the next generation accelerator magnets.
The UNIGE-Princeton research collaboration aims to understand the mechanism behind the performance degradation of superconducting wires under mechanical loads and, in particular, to establish a correlation between the imperfect structure of the superconducting filaments in the wires and the stress value corresponding to the occurrence of the irreversible degradation of the critical current. Our approach combines the quantitative analysis of the filament microstructure obtained from synchrotron tomography (link to a 3D reconstruction), characterization of the superconducting properties under mechanical loads and the numerical modelling of the imperfect wire micro-crack fracture mechanics.
EuCARD-2 is a research project co-funded by the European Commission under the FP7 Capacities Programme and coordinated by CERN. The objective is the advancement of the European accelerator infrastructures at the forefront of global research, where a consensus is growing towards the interest of more than doubling the present LHC energy. The project has 40 partners from 15 European countries. The list of partners include 10 accelerator laboratories, 23 technology institutes/universities, 5 scientific research institutes and 2 industrial partners. Our contribution focuses on the development of a first High Temperature Superconductor (HTS) magnet that has all requirements to constitute the high field insert of a 20 T dipole magnet for a High Energy-LHC (HE-LHC).
