R&D on ITER in-vessel magnetic sensors

摘要: Abstract This paper summarizes the progress of R&D activities related to design in-vessel magnetic sensors for measurement equilibrium field in ITER and associated mechanical support connection system. The background activities, developed last few years framework several collaborations, is provided introduction. focuses on experimental results obtained from a set sensor prototypes, recently manufactured tested, numerical simulations performed order verify compliance with requirements. finally illustrates status engineering analyses system, conceived be replaceable by remote handling. In conclusion, specific issues which require further developments achieve final are outlined.
