Development of Magnetic Field Diagnostics for Fusion Reactors
Original language description
Magnetic diagnostics play a crucial role in determining key parameters oftokamak plasmas, such as plasma position and shape. Traditional methods for measuringmagnetic fields during tokamak discharges rely on inductive sensors, such as pick-up coils.While these sensors are adequate for tokamaks with relatively short pulses and limitedradiation levels, fusion reactors with long pulse lengths and high radiation environmentsrequire the use of steady-state magnetic field sensors, such as Hall sensors. In this paper,the principles behind magnetic field measurement in the fusion plasma environmentwill be reviewed. The performance and drawbacks of pick-up coils will be described,and advancements in Hall sensor development for fusion reactors will be outlined. Thechallenges associated with the utilisation of Hall sensors in such environments will beaddressed, including the necessary techniques such as synchronous detection and currentspinning. Finally, the potential for data fusion of inductive and Hall sensors using theKalman filter algorithm to enhance measurement accuracy will be discussed.
