The DESC Stellarator Code Suite Part II: Perturbation and continuation methods [PDF]
arXiv.org, 2022 A new perturbation and continuation method is presented for computing and analyzing stellarator equilibria. The method is formally derived from a series expansion about the equilibrium condition $F \equiv J \times B - \nabla p = 0$, and an efficient ...

Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023 This paper presents the study of time‐fractional nonlinear fifth‐order Korteweg–de Vries equations by utilizing an adequate novel technique, namely, the q‐homotopy analysis transform method. The fifth‐order Korteweg–de Vries equation has got its importance in the study of magneto‐sound propagation in plasma, capillary gravity water waves, and the ...

Existence of an optimized stellarator with simple coils [PDF]
Journal of Plasma Physics, 2022 An optimized compact stellarator with four simple coils is obtained from direct optimization via a coil shape. The new stellarator consists of two interlocking coils and two vertical field coils similar to those of the Columbia Non-neutral Torus (CNT ...

International Journal of Energy Research, Volume 46, Issue 3, Page 2748-2770, 10 March 2022., 2022 Summary One of the most challenging objectives of the European research concerning nuclear fusion technology, promoted by the EUROfusion consortium, is to bring stellarator‐type nuclear fusion devices to maturity. To this purpose, studies on a large HELIcal‐axis advanced stellarator (HELIAS), extrapolated from Wendelstein 7‐X and based on a 5‐fold ...

Global gyrokinetic simulations of electromagnetic turbulence in stellarator plasmas
Journal of Plasma Physics, 2023 Global electromagnetic turbulence is simulated in stellarator geometry using the gyrokinetic particle-in-cell code EUTERPE. The evolution of the turbulent electromagnetic field and the plasma profiles is considered at different values of the plasma beta ...

Single-stage gradient-based stellarator coil design: stochastic optimization [PDF]
Nuclear Fusion, 2021 We extend the single-stage stellarator coil design approach for quasi-symmetry on axis from (Giuliani et al 2020) to additionally take into account coil manufacturing errors. By modeling coil errors independently from the coil discretization, we have the

Nuclear Fusion Pattern Recognition by Ensemble Learning
Complexity, Volume 2021, Issue 1, 2021., 2021 Nuclear fusion is the process by which two or more atomic nuclei join together to form a single heavier nucleus. This is usually accompanied by the release of large quantities of energy. This energy could be cheaper, cleaner, and safer than other technology currently in use.

Approach to nonlinear magnetohydrodynamic simulations in stellarator geometry [PDF]
Nuclear Fusion, 2021 The capability to model the nonlinear magnetohydrodynamic (MHD) evolution of stellarator plasmas is developed by extending the M3D-C 1 code to allow non-axisymmetric domain geometry.
