Overview of superconducting techniques for magnetic fusion devices

The basics of using the cable in conduit conductor (CICC) concept in new projects 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 cooling scheme, the way to avoid all coil preassembly tests, the support structure, vacuum vessel (VV) and cryostat design that could provide the best access to the device, load transfer from VV to cryostat and other design features of new projects are discussed.
