Next generation fusion and high energy physics machines will require high field magnets with the ability to operate at variable temperatures. Therefore, high current cables able to operate in such conditions will be required. As reaching magnetic fields higher than 16 T using traditional Low Temperature Superconductors can be challenging, the more recently investigated High Temperature...
In the quest for ultra-high-field magnets, one inevitable challenge is ever larger electromagnetic forces and their effect on the conductor. REBa2Cu3O7-x (REBCO) coated conductors have extraordinary transport and mechanical properties but how the vortex pinning and the external stresses are related is not well understood, especially when it passes the reversible strain of the conductor. This...
In the HTS superconducting magnet application fields like motors, generators, and SMES, 2G REBCO coated conductor (CC) tapes will be subjected to alternating stress or strain during manufacturing and operation. In these applications, the repeated load affects the mechanical integrity and eventually the electrical transport property of CC tapes. Therefore, mechanical and electromechanical...
REBCO coated conductors are promising candidates for high field (>25 T) user magnets. However, as the demand for higher fields increase, so does the potential to overstrain the conductors being used. Coated conductor substrates, such as 310 stainless steel and the super-alloy Hastelloy C276, serve as the backbone for mechanical strength in these conductors. Both substrate alloys share similar...
High quality 2G HTS tapes are desired for power applications, cables, and high field magnets. The original tape is fabricated in 12-40 mm widths, but most magnets and many cables require narrower tapes made by slitting the original tape. There are many advantages of narrow tapes: reduced magnetization loss, improved field quality, faster ramp time, reduced cryogen loss, and the opportunity...
