Amongst the range of prospective applications for bulk superconductors, the shielding of high magnetic fields at low frequency is extremely promising. Unlike conventional high permeability ferromagnetic materials which exhibit a relatively low saturation magnetization (e.g. µ0Msat ~ 0.75 T for mumetal), superconductors do not suffer from this drawback. They are therefore well suited to shield magnetic flux densities above 1 tesla. This can be achieved by hollow bulk superconductors of cylindrical geometry. The shielding efficiency and shielded volume are both strongly improved when the hollowed tube is closed at one extremity. As an example, we showed recently [1] that YBa2Cu3O7 (YBCO) tubes of ~ 10 mm inner diameter closed at one extremity and engineered by a buffer-aided top seeded melt growth fabrication process were able to attenuate axial flux densities of 1.5 T by a factor of 100 at 20 K. Such record performances are partly due to the presence of a cap at one extremity. The aim of the present work is to examine further and understand the influence of a cap on the shielding properties for various configurations. In this communication we investigate the shielding properties of hollow and semi-closed bulk superconducting tubes at 77 K. For the semi-closed configuration, we compare situations the cap is either placed against the extremity (with a small controllable gap between them) or welded naturally. The field to be shielded is either parallel or perpendicular to the main axis of the tube. Both YBCO tubes produced by buffer-aided top seeded melt growth and commercial Bi-2223 tubes are studied. The experimental results are compared to finite element numerical modelling carried out either in 2D (for the axial configuration) or 3D (for the transverse configuration). In the axial configuration, the results show that a small gap between the tube and the cap is not detrimental to the shielding properties. We also show that the shielded volume can be easily enhanced by increasing the thickness of the cap or its critical current density. In the transverse configuration, the results point out the crucial role of the superconducting joint between the tube and the cap. The need for a superconducting joint depends therefore on the main direction of the magnetic field to be shielded. References: [1] L. Wéra. et al., IEEE. Trans. Appl.

In 2016 and 2017, the Cassini Saturn orbiter executed a final series of high inclination, low-periapsis orbits ideal for studies of Saturn's polar regions. The Cassini Ultraviolet Imaging Spectrograph (UVIS) obtained an extensive set of auroral images, some at the highest spatial resolution obtained during Cassini's long orbital mission (2004-2017). In some cases, two or three spacecraft slews at right angles to the long slit of the spectrograph were required to cover the entire auroral region to form auroral images. We will present selected images from this set showing narrow arcs of emission, more diffuse auroral emissions, multiple auroral arcs in a single image, discrete spots of emission, small scale vortices, large-scale spiral forms, and parallel linear features that appear to cross in places like twisted wires. Some shorter features are transverse to the main auroral arcs, like barbs on a wire. UVIS observations were in some cases simultaneous with auroral observations from the Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS) that will also be presented. UVIS polar images also contain spectral information suitable for studies of the auroral electron energy distribution. The long wavelength part of the UVIS polar images contains a signal from reflected sunlight containing absorption signatures of acetylene and other Saturn hydrocarbons. The hydrocarbon spatial distribution will also be examined. [less ▲]

The land-sea interface is an extremely fragile environment. On a global scale, coastlines are threatened by a multitude of factors sometimes natural and mostly anthropogenic. Thus, in addition to the disruptions to coastal areas by port facilities, dams, sediment sampling on the beach or urban sprawl, there are the consequences of climate change, including rising sea levels. Studies conducted in West Africa show important shoreline erosion processes in recent years with many socio-economic consequences. [...] [less ▲]
