A quasi-isodynamic magnetic field generated by helical coils

Nuclear Fusion, 2019
This paper presents a set of continuous helical coils that generate a magnetic field showing characteristics of quasi-isodynamic magnetic configuration. The magnetic field generated by the coil system is similar to the quasi-isodynamic configurations of advanced stellarators with regard to the shape pattern of the flux surface and the field strength in

High-β island-divertor equilibria of a quasi-isodynamic stellarator

Plasma Physics Reports, 2013
A stellarator vacuum field is found for which free-boundary MHD quasi-isodynamic equilibria with a nearly invariant island structure in the vacuum field region surrounding the plasma are obtained for 〈β〉 values up to about 0.07.

Medium-β free-boundary equilibria of a quasi-isodynamic stellarator

Plasma Physics Reports, 2012
Free-boundary MHD equilibria with magnetic surfaces in the vacuum region surrounding the plasma [E. Strumberger, Nucl. Fusion 37, 19 (1997); M. Drevlak, D. Monticello, and A. Reiman, Nucl. Fusion 45, 731 (2005)] are obtained for a quasi-isodynamic stellarator [A. A. Subbotin, M. I. Mikhailov, V. D. Shafranov et al., Nucl. Fusion 46, 921 (2006); M.

Optimizing particle transport for enhanced confinement in quasi-isodynamic stellarators

Physical Review E
Despite significant advances in reducing turbulent heat losses, modern quasi-isodynamic (QI) stellarators -- such as Stellaris -- continue to suffer from poor particle confinement, which fundamentally limits their overall performance. Using gyrokinetic simulations within the GENE--Tango framework, we identify suppressed inward thermodiffusion, caused ...

Searching for SQuIDs: Stable Quasi-Isodynamic Designs as Fusion Reactor Candidates

Quasi-isodynamic (QI) stellarators are uniquely attractive fusion reactor candidates due to their good fast ion confinement and small toroidal currents, ensuring disruption-free ...
