Abstract
The Bi2212 cable-in-conduit conductor (CICC) is a composite soft material and is sensitive to stress-strain and brittle breakage. The cabling tensions are critical parameters for the CICCs and have undergone trial production many times to achieve effective cable control. Unreasonable tension will cause circumferential and axial motion, resulting in deflection bending, rotation fluctuations, and wire slip. This study investigated the manufacturing process of the Bi2212 CICC, optimizing the cable twisting process and reducing manufacturing consumption and damage. Additionally, optimized tensions of the Bi2212 CICCs during the cabling process, focusing on pay-off tension, rotation speeds, and traction tensions were presented. Finally, the results are tested and verified in the factory to examine the wire jumpers, serpentine bending, and pitch fluctuations. This research provides useful references for future cable fabrication of the HTS CICCs.
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.
