Description
Thea Energy, Inc. is currently developing the “Eos” planar coil stellarator, the Company’s first integrated fusion system capable of forming optimized stellarator magnetic fields without complex and costly modular coils. To demonstrate the field shaping capability required to enable a planar coil stellarator, Thea Energy designed, prototyped, and tested the "Canis" 3x3 array of high-temperature superconductor (HTS) planar coils after successfully demonstrating a single HTS planar coil prototype. Thea Energy manufactured nine demountable HTS planar coils and developed the cryogenic test and measurement infrastructure necessary to validate the array. Thea Energy assembled and operated the array at 20K, generating several stellarator-relevant field shapes and demonstrating closed loop field control of the superconducting magnets within a margin of error acceptable for stellarator operations. The Canis 3x3 magnet array test campaign provides a proof of concept for HTS planar shaping coils as a viable approach to confining stellarator plasmas.
