IPP said installation of new water-cooled inner cladding of the plasma vessel will make the Wendelstein 7-X facility suitable for higher heating power and longer plasma pulses.

The new cladding’s centrepiece, the so-called divertor, was manufactured by the institute’s Garching branch. It was delivered to Greifswald on 17 March and installation work will last until well into next year.

Fusion systems of the stellarator type promise high-performance plasmas in continuous operation. Accordingly, heat and particles from the hot plasma permanently stress the vessel walls. It is the task of the divertor – a system of specially equipped baffle plates to which the particles from the edge of the plasma are magnetically directed – to regulate the interaction between plasma and wall.

The upgrade of the world's largest stellarator-type fusion device - Germany's Wendelstein 7-X - is set to enter a new stage with the final delivery of components for the so-called divertor. Preparations for installation of the water-cooled inner cladding components have been completed, with installation work expected to continue well into next year.

Scientists at Germany’s Max Planck Institute for Plasma Physics (IPP) on 25 June reported a new record performance at the Wendelstein 7-X stellerator, which began operation in 2015. Earlier experiments saw the plasma in the reactor achieve higher temperatures and densities than ever before, and now the records have been broken again in a new test with upgraded components. Like the tokamak, the stellarator uses large superconducting magnets to suspend hydrogen plasma and heat it to the temperatures and pressures needed to fuse hydrogen into helium. The Wendelstein 7-X has 50 superconducting magnet coils some 3.5 metres high. However, while the tokamak confines plasma in a doughnut shaped torus, the stellarator traps the plasma in a twisting spiral shape, which is designed to cancel out instabilities in the suspended plasma.
