Wendelstein 7-X is the world’s largest fusion device of the stellarator type. Its objective is to investigate the suitability of this type for a power plant. It is testing an optimised magnetic field for confining the plasma.

Nov 30, 2016 · The Wendelstein 7-X (W7-X) stellarator experiment is the first representative of the new generation of optimized stellarators, and aims to show with its superconducting coil system and...

Jun 5, 2019 · Wendelstein 7-X is a high-iota, low shear stellarator with optimized magnetic field geometry and plasma volume. It is the mission of the device to demonstrate steady-state (pulse length ) generation and confinement of fusion-relevant hydrogen and deuterium plasmas.

Sep 9, 2024 · W7-X will now start the new experiment phase OP2.2 on 10 September 2024, having been significantly optimised. Numerous extensions, improvements and repairs were made to Wendelstein 7-X itself, the control and data acquisition systems, the heating systems and the almost 50 different plasma diagnostics.

Designers of the W7-X stellarator sought to reduce neoclassical transport by carefully shaping the complex, three-dimensional magnetic coils that create the confining magnetic field. To test the effectiveness of the design, researchers investigated complementary aspects of it.

Abstract W7-X is a fully optimised low-shear stellarator of the Wendelstein line. It follows the partially optimised W7-AS device which showed excellent operational characteristics at fusion relevant parameters. W7-X is optimised along the quasi-isodynamic principle.

Sep 14, 2022 · Wendelstein 7-X (W7-X) – the stellarator at the Max Planck Institute for Plasma Physics (IPP), Greifswald – has been significantly improved and will resume scientific experiments in autumn 2022.

Aug 11, 2021 · Here we demonstrate that such record values provide evidence for reduced neoclassical energy transport in W7-X, as the plasma profiles that produced these results could not have been obtained...

Auburn University researchers are working to advance the stellarator approach to magnetic fusion energy by investigating plasma physics in Wendelstein 7-X (W7-X), the world’s largest and most advanced optimized stellarator.

The Wendelstein 7-X (W7-X) is a fusion research device that uses the stellarator concept to confine plasma in a magnetic field. As of 2023, it is the world's largest stellarator device, and its main goal is to demonstrate the feasibility of continuous operation in a fusion power plant.
