Abstract: It has been more than 25 years since the discovery of High Temperature Superconductors and following their utilization in power cable applications and layer-wound magnets, they are now being considered for future high-current, high-field magnets typically used in high-energy physics and fusion machines. Several cables design are currently under study using both YBCO and BSCCO conductors. In this talk a brief review of the different cables options will be presented with focus on the experimental studies performed on the High-Current Twisted Stacked-Tapes Cable (TSTC) design. An overview of the research activities performed at Tufts will be given starting from electromechanical behaviors of LTS Nb3Sn to the electromechanical behaviors of REBCO tapes and TSTC cables for their use in high field, high current magnets. The experimental and numerical methodologies to understand the bending, torsion, transverse and axial behaviors of those conductors will be discussed.
