Maple leaf antiferromagnet in a magnetic field

Frédéric Mila, Pratyay Ghosh, Ronny Thomale

We analyze the quantum antiferromagnet on the maple leaf lattice in the presence of a magnetic field. Starting from its exact dimer ground state and for a magnetic field strength of the order of the local dimer spin-exchange coupling, we perform a strong-c ...

Characterization of the Radiation Resistance of Glass Fiber Reinforced Plastics for Superconducting Magnets

Sandra Sequeira Lopes Tavares

The overall performance of accelerator magnets strongly relies on electrical and mechanical robustness of their components. With an increase of the energy, future particle accelerators will have to withstand integral doses of ionizing radiation of up to se ...

Diffusion-Bonding Between Strands and Modeling of Splices of Nb3Sn Rutherford Cables

Pierluigi Bruzzone, Kamil Sedlák, Nikolay Bykovskiy

Particle accelerators foresee the use of Nb3Sn in the next generation of dipole magnets. A common design strategy is to grade the coil, i.e., to optimize the quantity of superconductor in the turns with respect to the magnetic field intensity. As a consequ ...

Preliminary Design of a High Current R&W TF Coil Conductor for the EU DEMO

Pierluigi Bruzzone, Kamil Sedlák, Federica Demattè

Paschen failures in ITER, W7-X and JT60 superconducting coils at the acceptance tests have shown that it is highly desirable to lower the coil discharge voltage (U-d) of the DEMO Toroidal Field (TF) coils. Another benefit of lowering the U-d might be the r ...

Modeling of Quench Protection Concepts for Canted-Cosine-Theta Type High-Field Magnets

Andreas Pautz, Bernhard Auchmann, Jiani Gao

An innovative high-field superconducting magnet of Canted-Cosine-Theta (CCT) type has been proposed for Future Circular Collider 16 T dipole magnet design. The unique mechanical structure intercepts the accumulated forces lowering the stress on the winding ...

Magnetic and Mechanical 3-D Modelling of a 15 T Large Aperture Dipole Magnet

Pierluigi Bruzzone, Luca Bottura, Douglas Martins Araujo

In 2018, two structures have been proposed with the goal of replacing the magnetEDIPOthat stopped operating in 2016. These two solutions were designed to generate a field of 15 T on an aperture of 100 x 150 mm2 at 4.2 K by using Nb 3Sn superconducting Ruth ...

Unconventional Spin Relaxation Involving Localized Vibrational Modes in Ho Single-Atom Magnets

Harald Brune, Stefano Rusponi, Marina Pivetta, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Aparajita Singha, Romana Baltic, Katharina Johanna Diller

We investigate the spin relaxation of Ho single atom magnets on MgO/Ag(100) as a function of temperature and magnetic field. We find that the spin relaxation is thermally activated at low field, while it remains larger than 1000 s up to 30 K and 8 T. This ...

Force and Torque Model of Ironless Passive Magnetic Bearing Structures

Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego

This article presents the development and validation of a three-dimensional force and torque semi-analytical model for ironless permanent magnet structures. This method relies on the definition of the magnetic flux density generated by permanent magnets in ...
