694. Superconducting characterization of prototype LTS samples

Mattia Ortino (TU Wien (Vienna))

6/27/19, 3:30 PM

Presentation

695. Microstructural characterisation of superconducting materials

Alice Moros (Technische Universität Wien)

6/27/19, 3:48 PM

Presentation

This presentation shows the current status of the microstructural analyses concerning several superconducting materials, envisioned for diverse components of the Future Circular Collider: Nb3Sn, YBCO, MgB2 (Magnets), Tl-1223 (Beam screen) and NbN (RF Cavities). All the samples have to be properly prepared in order to be consequently well characterized by employing different electron microscopy...

696. Assessment of high-performance superconducting wires at low temperatures

Johannes Gnilsen

In earlier study a 3 T pulsed electromagnet was the key tool in our experiments. Short pieces (of 20 cm length) of long tapes have been introduced in the magnet channel of the magnet and loaded with up to 10 A transport current. The voltage signal during the magnetic field pulse has been recorded and interpreted in terms of an “extended alpha approximation” approach. To develop this model, the...

697. Fluid properties modeling

Jakub Tkaczuk

6/27/19, 4:24 PM

Presentation

Based upon the conceptual design reports for the FCC cryogenic system, the need for more accurate thermodynamic property models of mixtures was identified. Both academic institutes and world-wide industries have identified the lack of reliable equation of state for mixtures used at very low temperatures. Detailed cryogenic architecture modeling and design cannot be assessed without valid fluid...

698. Production of high temperature superconducting Thallium-based thin-film coatings

Aisha Saba (CNR-SPIN)

6/27/19, 4:42 PM

Presentation

The study of high-energy Future Circular Collider (FCC-hh) study includes investigation on thallium based high temperature superconducting materials to act as part of the beam screen for the circulating high energy proton beams stability. At present, the copper coating is used to keep the beam coupling impedance low, but at 50K it might not be sufficiently low. For beam stability, high-...
