Contribution méthodologique à la conception de systèmes supraconducteurs de lévitation magnétique

Not available.Ce mémoire de thèse propose une contribution méthodologique à la conception de systèmes magnétiques pour la lévitation magnétique qui repose sur la compensation de la gravité à l'aide d'une force magnétique. Il établit la corrélation existant entre la valeur de la force de lévitation, l'induction, la taille de la zone utile et l'homogénéité du champ de force résiduel. Après un état de l'art et une présentation des applications potentielles de la lévitation magnétique, une méthodologie de résolution de la synthèse de source pour la lévitation magnétique dans le cas des géométries bidimensionnelles invariantes par translation est proposée. Puis, deux structures supraconductrices destinées à la lévitation de l'eau et à celle de cibles de deutérium ont été dimensionnées. Ensuite l'association d'enroulements supraconducteurs et d'inserts ferromagnétiques est abordée. Enfin, le dernier chapitre expose les résultats expérimentaux dans le cas de la lévitation de l'hydrogène liquide

Editorial of the MADMAX Special Section

International audienceThe present IEEE Transactions on Applied Superconductivityissue provides a global overview of the scientific and technological development related to the superconducting magnet of the MADMAX experiment. The objective of the experiment is to detect axion in the 100 µeV mass range that would explain several mysteries of high-energy physics and cosmology (absence of CP violation, dark matter candidates, inflation and structure formation in the early universe). The MADMAX experiment will consist of multiple parallel dielectric disks, the so-called booster, hosted in a high magnetic field dipole. To host the booster, the 10 T superconducting dipole must have a large aperture of 1.3 m in diameter leading to a figure of merit of the order of 100 T2m2. The project is led and funded by the Max Planck Institut für Physik, who selected CEA Saclay to perform the R&D developments required to manufacture such a large-scale superconducting dipole

Effect of Eddy Currents Induced in the Thermal Shield During the Quench of the Superconducting Coils for the Super-FRS of the FAIR Project

International audienceThe Superconducting FRagment Separator (Super-FRS) is a two-stage separator to be built next to the site of GSI, Darmstadt, Germany, as part of Facility for Anti-Proton and Ion Research. Its purpose is to create and separate rare isotope beams and to enable the mass measurement also for very short lived nuclei. Overall, the Super-FRS consists of 24 dipole magnets of so-called superferric type, with superconducting coils but the field shaped by magnetic iron. The coil is trapezoidal-shaped configuration, which is wound with NbTi wires of high Cu/Sc ratio and located inside a cryostat equipped with a thermal shield and cooled with liquid helium; but the dipole will have a warm iron yoke with a wide air trim slot. This paper presents the results of the eddy current calculations in the thermal shield induced during the quench of the magnet. The mechanical behavior of the thermal shield under the Lorentz forces generated by the eddy currents will also be presented

Status of the Super-FRS Magnet Devlopment for Fair

The Super FRS is a two-stage in flight separator to be built next to the site of GSI, Darmstadt, Germany as part of FAIR (Facility for Anti-proton and Ion Research). Its purpose is to create and separate rare isotope beams and to enable the mass measurement also for very short lived nuclei. Due to its three branches a wide variety of experiments can be carried out in frame of the NUSTAR collaboration. Due to the large acceptance needed, the magnets of the Super-FRS have to have a large aperture and therefore only a superconducting solution is feasible. A superferric design with superconducting coils was chosen in which the magnetic field is shaped by an iron yoke. We will present the actual design status of the dipole- and multipole magnets as well as the status of the development of the dedicated test facility at CERN
