Suppression of tearing modes by External Rotational Transform in a Tokamak-Stellarator hybrid configuration on J-TEXT

Nuclear Fusion
A Tokamak-Stellarator hybrid configuration has been established on the J-TEXT tokamak by the application of stellarator-like External Rotational Transform (ERT) coils.

Remote-Steering Antennas for 140 GHz Electron Cyclotron Heating of the Stellarator W7-X

EPJ Web of Conferences, 2017
For electron cyclotron resonance heating of the stellarator W7-X at IPP Greifswald, a 140 GHz/10 MW cw millimeter wave system has been built. Two out of 12 launchers will employ a remote-steering design. This paper describes the overall design of the two

Optimization of stellarator configurations combining omnigenity and piecewise omnigenity [PDF]

Nuclear Fusion
We present a method for optimizing stellarator configurations that combine omnigenity and piecewise omnigenity (pwO). Within the \texttt{OOPS} optimization framework [Liu \textit{et al.}, arXiv:2502.09350 (2025)], we introduce a mapping technique that ...

Electromagnetic coil optimization for reduced Lorentz forces

Nuclear Fusion
The reduction of magnetic forces on electromagnetic coils is an important consideration in the design of high-field devices such as the stellarator or tokamak.

Stellarator Optimization with Poloidal Field Coils

, 2021
Stellarators are devices that use magnetic fields to optimize the conditions needed for plasmas to undergo fusion. Unlike tokamaks, stellarators do not rely on a plasma current but can produce a helical magnetic field using only external coils.

Minimization of magnetic forces on Stellarator coils

, 2021
Magnetic confinement devices for nuclear fusion can be large and expensive. Compact stellarators are promising candidates for costreduction, but introduce new difficulties: confinement in smaller volumes requires higher magnetic field, which calls for ...

CIEMAT-QI4X: a reactor-relevant quasi-isodynamic stellarator configuration compatible with an island divertor

Nuclear Fusion
A four-field-period quasi-isodynamic stellarator configuration is presented that exhibits small neoclassical and electrostatic turbulent transport, good fast-ion confinement over a wide range of β values, small bootstrap current and an edge island ...

Winding angle optimization and testing of small-scale, non-planar, high-temperature superconducting stellarator coils

Superconductors Science and Technology
We designed and constructed two non-planar coils with high-temperature superconductors (HTS) based on shapes from the Wendelstein 7-X stellarator. Tape track orientation of the HTS was optimized to reduce the coil size as much as possible while staying ...
