596. Can Stainless Steel Meet the Challenges of Future Cryogenic Engineering Systems?

Ignacio Aviles Santillana (CERN)

ICMC 10: Structural and 3D printed materials processing and properties

Invited Oral (30m)

As the demands on cryogenic engineering systems continue to evolve with advancements in high-energy physics, novel fusion devices, and the expanding hydrogen economy, the question arises: can stainless steel rise to the challenge? Relying in superconducting magnet technology, the magnetic fields required for a variety of very ambitious engineering projects are increasingly high: 16 T for FCC –...

346. Transverse stress limits of Bi-2212 Rutherford cables at 11 T, 4.2 K

ICMC 04: Superconducting cables processing properties

Regular Oral (15m)

For high-field accelerator magnets of the future, Bi-2212 round wires are an interesting option thanks to superior Jc compared to Nb3Sn for magnetic fields above 13 T. The round shape of the wires makes it possible to use established Rutherford cabling technology. The large thermal margin results in training-free coil demonstrators. In accelerator magnets, however, Bi-2212 Rutherford cables...

116. Onset of mechanical degradation due to transverse compressive stress in Nb3Sn Rutherford cables as a function of heat treatment and impregnation.

ICMC 08: Stress & Strain & Radiation effects, Aging, Fatigue and life cycle analysis

Regular Oral (15m)

This work presents observations on crack formation in Nb3Sn Rutherford cables that underwent a variation in the heat treatment cycle and the
resin used for impregnation. The main purpose of the study is to compare
the crack initiation limits and propose a combination of parameters to improve the mechanical strength of the cables. While lowering the final dwell
time of the heat treatment...

404. Design and application of HTS magnet for magneto-hydro-dynamic plasma shielding in radio blackout and heat flux mitigation experiments

Sonja Schlachter (Karlsruhe Institute of Technology)

ICMC 11: Aircraft and Space application, materials and properties

Poster Presentation (120m)

Since the early days of space flight, the so-called radio-blackout phenomenon occurring during hypersonic flight or during atmospheric entry into a celestial bodies’ atmosphere is well known. The compressed and partially ionized species in the hot plasma in front of the spacecraft can block radio waves leading to a complete loss of communication with ground stations, data telemetry, and GPS...

19. The mechanical research on high strength CICC jacket with YS>1500MPa@4.2K used for future fusion magnets

Weijun Wang

ICEC 10: Cryogenic applications: large magnet systems

Poster Presentation (120m)

Increasing magnetic field intensity in limited space is an important strategy to obtain high parameter plasma and improve the fusion power. The next generation of fusion magnets will have a peak magnetic field greater than 17T, such as China Fusion Engineering Test Reactor (CFETR) central solenoid magnet. The development of high strength and high toughness jacket has become one of the...

332. Impact of hydrogen embrittlement on cryogenic mechanical properties of 304 steel

Klaus-Peter Weiss (KIT, Institute for Technical Physics)

24/07/2024, 12:45

ICMC 12: Hydrogen technology materials, structures and techniques

Regular Oral (15m)

Within the framework of the “AppLHy!” pilot project, the Karlsruhe Institute of Technology (KIT) is investigating the transport and application of liquid hydrogen (LH2). Due to the advantages of LH2, such as high energy density, high purity, storage at low pressure and the possible facilitation of the available cryogenic temperature level, various application scenarios are being...
