| Abstract: | The muon collider is a proposed particle accelerator in which collisions with very high energies can be performed. In the muon collider various magnets are needed, of which the target and capture magnet is one of the most complex ones. To generate high fields for these magnets, superconductors are used. Currently, the ReBCO High-Temperature Superconductor is being researched for its great operating range. Unfortunately, ReBCO is a brittle material making it important to study its mechanical limits. ReBCO is made in the form of tapes and these tapes can be stacked to achieve a high current. In this study, the bending limits of stack cables are studied experimentally while focusing on the dependence of the amount of tapes in the stack on these bending limits. In this work, soldered stack cables of 5 and 10 tapes were made using a soldering tool. In the experiments, these two cables were compared, which showed that the 10-tape stack experienced more critical current degradation than the 5-tape stack for the three different bending radii that were tested. After bending both cables to the radius of 50 mm, visible damage in the form of separation between the tapes was observed in both cables. |
