Project ITER aims to build the largest fusion device in the world, with the goal of demonstrating the scientific and technical feasibility of fusion power. The magnetic diagnostics system in ITER is very critical, since it allows the measuring and controlling in the real time plasma parameters. The magnetic sensor to monitor the instability in the local magnetic field will be installed in a harsh environment characterized by severe neutron radiation, thermal loads, and ultra-high vacuum environment. Reliable diagnostics operation in harsh environments necessitate special material requirements to lower the adverse effects of neutron radiation and heat loads. Magnetic sensors made of ceramic layers with printed thin metallic conductors considered to form a monolithic structure are compatible with this high temperature, vacuum, and neutron radiation conditions. This work describes the development and fabrication of a novel inductive magnetic sensor using Low temperature cofired ceramic (LTCC) technology to measure the variation in the magnetic field. This work also addresses the mechanical and electrical characterizations performed on the sensor coils that results in the manufacturing of a reliable LTCC sensor for the ITER magnetic inner vessel coil.
