Abstract

An experimental superconducting eddy current braking prototype was designed, constructed and thoroughly evaluated. The components of the apparatus were accurately described, and heat leakage was calculated. The results showed that the heat leakage was 0.53 W at 5 K and 19.2 W at 40 K. The selected cryogenic system met the operational requirements of the apparatus. The fabrication process was outlined, and the apparatus was tested with the integrated cryogenic system. The device successfully cooled to the target temperature. The circular coil, carrying a current of 180 A, generated a braking force of 0.7 kN at a speed of 400 km/h, while the racetrack coil, at 50 A, produced 0.15 kN at the same speed. The experimental results were consistent with the analysis, demonstrating the successful operation of the prototype throughout the testing phase.

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
