In the recent newsletter published on the Max Planck Institute for Plasma Physics website you can learn more about the preparation of the Wendelstein 7-X stellarator for the next experimental campaign.
Significant developments refer to the construction elements of the W7-X. Now, the divertor will be water-cooled as opposed to earlier operation with uncooled wall cladding. Thanks to the changes introduced, it will be possible to study plasma at a maximum heating energy of 18 GJ for 30 minutes.
Additionally, the system of plasma heating will be expanded with a new NBI (Neutral Beam Injector) system which is now being extended to two neutral beam injectors with two sources each and a total heating power of 7 MW (particle energy 55 keV) for the injection of hydrogen ions.
