Wed-Or9: Stress & Strain Effects
- Jun Lu
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 –...
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...
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...
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...
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...
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...
