Description
Thea Energy has created the “Canis” 3x3 array of high-temperature superconducting (HTS) planar coil magnets as a prototype for the “Eos” stellarator. This poster covers instrumentation of the Canis 3x3 magnet array highlighting the magnetic field control and field validation support systems. Field sensors mounted on each coil combined with individual magnet power supplies allowed the array field to be driven to stellarator relevant shapes with real-time feedback. The field shape and field error produced by the Canis 3x3 magnet array was validated with a hall effect probe mounted to a magnetic field scanning gantry placed on top of the array’s vacuum vessel. The planar coil magnets were equipped with one of three separate temperature and voltage profiles based on resolution required. This instrumentation configuration allowed for a per-coil testing scheme that eased machine maintenance through promoting modular, separate-system testing.
