Abstract
Practical REBCO bulk superconductor-based components and devices as rotational and linear magnetic bearings are well understood. A high-stiffness high temperature superconductor (HTS) magnetic bearing with 0.1 mm low-hysteresis is demonstrated for narrow-gap operation. Linear magnetic bearings up to 10-ton load have been successfully implemented in linear Maglev trains under real outside conditions. The REBCO bulk-based magnetic levitated (Maglev) trains are proposed for urban and low-speed transport concepts. On the contrary, high-mobile, lightweight, and flexible HTS bulk components are developed under the extreme and safe conditions of manned spaceflight for astronomy and space application. YBCO bulk proton irradiation tests for space application are presented. In the International Space Station (ISS), the interaction of the earth magnetic field with a perfect fast-moving diamagnet within a project called Magvector/MFX is measured and investigated. We compare an anticipated model with space experiments performed in the last two years in the ISS. The paper will summarize recent progress in this field, and present how cryogenic and HTS component design can positively impact levitation and screening performance. Properties of cryogenic systems and devices of mobile applications in their complexity and required robustness will be compared to stationary HTS systems, and the effect of different cooling options has to been considered.
