The superconducting solenoid for the muon source to be installed in the future second target station of materials and life science experimental facility of J-PARC is required to be highly radiation resistant. Over a 10-year operation period, the superconducting solenoid is expected to reach an absorbed dose of 100 MGy and a neutron fluence of 7.8$\times10^{22}$ $n/m^{2}$. A research and...
The US Magnet Development Program is considering REBCO symmetric tape round (STAR®) wires as candidates for the next generation of high-field hybrid magnets for high-energy particle colliders. In high-field dipole magnets, the conductors experience strong mechanical loads transverse to their longitudinal axis. The current-carrying capability of the superconductor may decrease under these...
This study investigates the impact of nickel-plated YBCO (Yttrium Barium Copper Oxide) tapes on current sharing levels and performance, as compared to traditional copper-wrapped tapes. Prior simulations demonstrated a correlation between defect density and current sharing levels, prompting an experimental evaluation. Nickel-plated tapes were utilized to enhance thermal conductivity by...
Understanding the dependence of the critical current, I$_c$, on magnetic field intensity and orientation, as well as on temperature is essential for developing reliable models for REBCO tape-based magnet design. This knowledge is particularly critical for advancing ultra-high-field magnets (20–40 T) required for applications ranging from fusion and particle accelerators to high-field science....
This is a comparative study of the angular critical current ($I_c$) in different REBCO coated conductors (CC) at high magnetic fields ($B < 45$ T) performed with torque magnetometry (US Patent 12,187,540)
The high $I_c$ of REBCO makes transport measurements challenging at low temperatures ($T$) and high $B$, which are crucial for magnet construction and pinning mechanism studies. On the...
