ATS Seminar - High Temperature Superconductivity: status, present and future applications
/ Ballarino, Amalia (speaker) (CERN)
Speaker
Amalia BALLARINO (TE-MSC-HSD)
Abstract
In recent years, High Temperature Superconductors (HTS) have attracted growing interest. Their intrinsic characteristics — specifically their ability to carry high currents at higher temperatures and in stronger magnetic fields compared to conventional superconductors — hold the potential to revolutionize a wide range of technologies [...]

Design of a multipurpose test facility (MTF) for HTS cables
/ Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Masci, Marco (CERN) ; Perini, Diego (CERN)
The High Field Magnet (HFM) program foresees, among others, the systematic measurement and assessment of mechanical, thermal, and electrical properties of high temperature superconductors (HTS) cables. These measurements are a key factor to characterize the conductor, verify its performance and control the production quality. [...]

A system solution for a 100 kA class high temperature superconducting line for HL-LHC and for wider energy applications
/ Ballarino, Amalia (CERN) ; Bailey, Wendell (U. Southampton (main)) ; Barth, Christian (CERN) ; Cruikshank, Paul (CERN) ; Gahier, Vanessa (CERN) ; Leclercq, Yann (CERN) ; Pasdeloup, Florian (CERN) ; Willering, Gerard (CERN) ; Yang, Yifeng (U. Southampton (main))
The powering of the High Luminosity magnets of the Large Hadron Collider relies on Cold Powering Systems incorporating direct current superconducting lines, called Superconducting Links, based on magnesium diboride cables. A Cold Powering System interconnects the magnets in the accelerator existing tunnel to the power converters in newly excavated galleries that are about 8 m higher than the accelerator tunnel and up to about 100 m distant from the magnets. [...]

Safety at HL-LHC IT String during construction, commissioning, and operation
/ Bozzini, D (CERN) ; Bajko, M (CERN) ; Ballarino, A (CERN) ; Blanchard, S (CERN) ; Gascon, J (CERN) ; Heredia, N (CERN) ; Onufrena, A (CERN) ; Perin, A (CERN) ; Rodriguez Mateos, F (CERN) ; Yammine, S (CERN) et al.
The HL-LHC IT String, a test facility for the major components of the HL-LHC Inner Triplet, is currently in its construction and commissioning phases in a surface building at CERN. The primary motivation of the HL-LHC IT String is to study and validate the collective behaviour of its different subsystems which include mainly: the inner triplet superconducting magnets and their correctors, a novel superconducting link, the cryogenics infrastructure for the cooling and quench recovery, the powering and quench protection systems, and the remote alignment system.

Development, Fabrication & Test of the Round, Multi-Layer REBCO Cables of the Cold Powering Systems of the HL-LHC
/ Barth, C (CERN) ; Saba, A (CERN) ; Leclercq, Y (CERN) ; Ballarino, A (CERN)
The magnets of the High Luminosity Upgrade of the Large Hadron collider (HL-LHC) will be electrically connected through Cold Powering Systems incorporating superconducting, 100 kA class, power transmission lines to direct current power converters in service galleries. These transmission lines or ‘Superconducting Links’ are based on multi-circuit magnesium di-boride ($\text{MgB}_{2}$) cables in 74.5–120 m long flexible cryostats. [...]

Design of Superconducting Magnetic Energy Storage (SMES) for Waterborne Applications
/ de Toledo, Carlos Hernando López (Comillas Pontifical U.) ; Munilla, Javier (Madrid, CIEMAT ; Comillas Pontifical U.) ; García-Tabarés, Luis (Madrid, CIEMAT) ; Gil, Carlos ; Ballarín, Nicolas (Comillas Pontifical U.) ; Orea, Javier (Comillas Pontifical U.) ; Iturbe, Rafael ; López, Borja ; Ballarino, Amalia (CERN)
The shift from fossil fuel to electric based propulsion in the waterborne transport sector has been sped up by recent policies aiming to reduce the sector emissions. This trend creates highly electrified vessels, with needs for energy storage systems (ESS) to satisfy the power demand affordably and to increase the on-board grid reliability and efficiency. [...]

Iron-based superconducting (IBS) wires fabricated through the powder-in-tube (PIT) method are prospective candidate materials for high magnetic field applications. In order to meet the requirements of such applications, it is important to obtain practical conductors with high transport critical currents at a competitive cost. [...]
