Electromagnetics aspects in ITER: impact on magnet cryogenics, plasma diagnostics and control system11Work performed under EURATOM study Contracts in the framework of the EC ITER Hometeam activities

The paper deals with some electromagnetic aspects of interest for their impact on the ITER project. In particular the following topics are illustrated: • feedback control of the distance between plasma separatrix and first wall; • identification of the plasma separatrix from signals detected by magnetic sensors; • ohmic losses in the cold structures, during normal operation scenario and plasma disruptions. The numerical results, which mainly refer to the ITER TAC-8 configuration, are discussed in the paper with the aim of contributing to the still open ITER design options.
