Abstract Text:
The Columbia Stellarator eXperiment (CSX), currently in the design phase, will confine a small aspect ratio quasiaxisymmetric plasma with an interlinked coil system. The magnetic field will be generated by a set of two planar poloidal field coils alongside two shaped interlinked coils (IL coils), with the potential consideration of additional coils to enhance shaping or experimental flexibility. The PF coils and vacuum vessel are repurposed from the former Columbia Non-Neutral Torus (CNT) experiment. HTS tape will be wound on a 3D printed bobbin to form the IL coils. These coils undergo shape and strain optimization to produce the desired plasma configuration while adhering to numerous engineering constraints. Single-stage optimization techniques are employed, where plasma and coils are optimized concurrently. Despite an increased problem complexity due to the larger number of degrees of freedom, these
methods find optimized plasma shapes that can be generated by coils adhering to engineering constraints. Once operational, CSX will validate quasiaxisymmetry physics, including impacts on flow damping and energetic particles.
