Optimization of quasi-symmetric stellarators with self-consistent bootstrap current and energetic particle confinement
Optimization of quasi-symmetric stellarators with self-consistent bootstrap current and energetic particle confinement
Quasi-symmetry can greatly improve the confinement of energetic particles and thermal plasma in a stellarator. The magnetic field of a quasi-symmetric stellarator at high plasma pressure is significantly affected by the bootstrap current, but the computational cost of accurate stellarator bootstrap calculations has precluded use inside optimization. Here, a new …
