Nuclear Materials and Energy, 2019 A deep understanding of the plasma-wall interaction processes in fusion devices like Wendelstein 7-X is necessary for an efficient plasma operation and a long lifetime of the plasma-facing components.In this work we present an approach employing residual

Configuration Space Control for Wendelstein 7‐X [PDF]
Contributions to Plasma Physics, 2010 AbstractThe Wendelstein 7‐X stellarator (W7‐X) is a superconducting fusion experiment presently under construction at the Greifswald branch of the Max‐Planck‐Institut für Plasmaphysik in Greifswald, Germany. W7‐X is a device with extreme geometrical complexity due to the close‐packing of components inside the cryostat and their complex three ...

Investigation of Optically Grey Electron Cyclotron Harmonics in Wendelstein 7-X [PDF]
EPJ Web of Conferences, 2019 For a magnetic field of 2.5T, the electron cyclotron harmonics are spectrally well separated in W7-X as it has a large aspect ratio. Because of this advantage from the geometry of W7-X stellarator, it is easier to scan these higher harmonics (70,140,210….

Status of Wendelstein 7-X construction [PDF]
Fusion Engineering and Design, 2007 Abstract Wendelstein 7-X (W7-X) is a fully optimised low-shear stellarator and shall demonstrate the reactor potential of a HELIAS-type fusion device. It is presently under construction at the Max-Planck-Institute for Plasmaphysics (IPP), Greifswald site.

The Thomson scattering system at Wendelstein 7-X [PDF]
Review of Scientific Instruments, 2016 This paper describes the design of the Thomson scattering system at the Wendelstein 7-X stellarator. For the first operation campaign we installed a 10 spatial channel system to cover a radial half profile of the plasma cross section. The start-up system is based on one Nd:YAG laser with 10 Hz repetition frequency, one observation optics, five fiber ...

WENDELSTEIN 7-X at the transition to assembly [PDF]
Fusion Engineering and Design, 2005 Abstract The WENDELSTEIN 7-X (W7-X) represents the continuation of fusion experiments of the stellarator type at the Max-Planck Institute for Plasma Physics. The experiment W7-X is built at Greifswald in the northeast of Germany. The size of the device (725 t, height of approximately 4.5 m, diameter approximately 16 m), a superconductive magnet ...

On‐Chip Neo‐Glycopeptide Synthesis for Multivalent Glycan Presentation
Chemistry – A European Journal, Volume 26, Issue 44, Page 9954-9963, August 6, 2020., 2020 Interactions of proteins with glycans rely on multivalency, where multiple adjacent binding events are involved. To study this glycan density‐dependent binding, a facile technique to synthesize peptide‐based multivalent carbohydrate scaffolds in parallel, directly on‐chip, in the microarray format, was developed.

Diagnostic setup for the divertor manipulator at wendelstein 7-X
Nuclear Materials and Energy, 2019 The investigation of plasma wall interactions in terms of erosion processes, fuel retention and new plasma facing components exhibits a scientific gap as discharges in tokamaks and stellarators last only seconds up to a minute.
