Modeling of Injected Current Stream-Induced 3D Perturbations in Local Helicity Injection Plasmas
C. E. Schaefer, A. C. Sontag, N. M. Ferraro +2
Solenoid-free tokamak startup techniques are essential for spherical tokamaks and offer a pathway to cost reduction and design simplification in fusion energy systems. Local helici…
