Overview of superconducting techniques for magnetic fusion devices

The basics of using the cable in conduit conductor (CICC) concept in new pr ojects for magnetic fusion devices as well as the need to improve the CICC design are discussed. Preference is given to a regular inner structure with respect to the usually considered loose one. Optimal solutions for the coo ling scheme, the way to avoid all coil pre-assembly tests, the support stru cture, vacuum vessel (VV) and cryostat design that could provide the best a ccess to the device, load transfer from VV to cryostat and other design fea tures of new projects are discussed.
