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 ...

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.

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….

Optimization of flux-surface density variation in stellarator plasmas with respect to the transport of collisional impurities [PDF]
, 2019 Avoiding impurity accumulation is a requirement for steady-state stellarator operation. The accumulation of impurities can be heavily affected by variations in their density on the flux-surface.

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.
