A high temperature superconductor accelerator demonstrator dipole magnets are currently under development in frame of the EuCARD2 project. Accelerator magnets require conductor with high overall current density, high field quality and large transverse stress tolerance. REBCO materials which possess uniquely high transport currents at low temperatures and high fields are challenging due to the...
Advanced Conductor Technologies has been developing Conductor on Round Core (CORC®) cables and wires wound from REBCO coated conductors for use in high-field magnets. An overview of the current status future developments of the CORC® cables and wires is presented. CORC® cables with thickness of 5 to 8 mm have been developed for use in larger magnets that require only very limited bending of...
Coated conductors are now being considered for use in beam steering and focusing magnets for high energy particle accelerators. However, coated conductors and cables have substantial magnetization, important for field quality. Magnetization decay, although suppressed, is also important for field quality retention. In this work we investigate the influence of applied current and selected field...
The CORC cable is composed of several layers of helically wound HTS tapes on a round core with the winding direction reversed in each successive layer. The cable is flexible but the flexibility is limited by the critical strain value when causing breakage of the HTS layer. The cables for magnets in fusion reactors experience large mechanical and electromagnetic loads arising from cabled...
Two new record size ReBCO CORC Cable-In-Conduit-Conductors were designed and manufactured by CERN in collaboration with the CORC strand supplier ACT in Boulder, and tested in cooperation with the Sultan team at PSI. The cables in both conductors are of similar design and use the six-around-one cable layout with six CORC strands. The cables are 2.8 m in length, rated 80 kA at 12T/4.5K and...
Two prototype Nb3Sn cable-in-conduit (CICC) conductors were designed and manufactured for the Toroidal Field (TF) magnet system of the envisaged European DEMO fusion reactor. Though both conductors were designed to operate at 82 kA in a background magnetic field of 13.6 T, they reflect a different approach with respect to the magnet winding pack assembly. The first approach is based on React &...
