How turbulence spreading improves power handling in quiescent high confinement fusion plasmas

Communications Physics
Viable magnetic fusion devices necessitate combining good confinement with effective power flux handling. A major concern for ITER, and devices beyond, is the divertor heat load width, which sets peak boundary heat loads on the plasma-facing materials ...

Gas puff imaging of plasma turbulence in the magnetic island scrape-off layer of W7-X

Nuclear Materials and Energy
The turbulence characteristics of the scrape-off-layer (SOL) plasma in the W7-X stellarator are investigated using a gas-puff-imaging (GPI) diagnostic, newly installed and operated during the OP 2.1 campaign.

Width of turbulent SOL in circular plasmas: A theoretical model validated on experiments in Tore Supra tokamak

Nuclear Materials and Energy, 2017
The relation between turbulent transport and scrape off layer width is investigated in circular plasmas toroidally limited on the inner wall. A broad set of experimental observations collected in the Tore Supra scrape off layer is detailed and compared ...

Robust Bio‐Textiles Via Mycelium‐Cellulose Interface Engineering

Advanced Functional Materials, EarlyView.
This work introduces a new class of sustainable textiles by growing mycelium, the root‐like structure of fungi, into cellulose‐based fabrics. This semi‐interpenetrating mycelium‐cellulose fiber network combines the strength and breathability of natural fibers with the water‐resistant and adhesive properties of mycelium, resulting in a robust, scalable,

Selected methods of electron-and ion-diagnostics in tokamak scrape-off-layer

Nukleonika, 2015
This invited paper considers reasons why exact measurements of fast electron and ion losses in tokamaks, and particularly i n a scrape-off-layer and near a divertor region, are necessary in order to master nuclear fusion energy production.

On scaling laws in scrape-off-layer plasmas

Plasma Physics and Controlled Fusion, 1994
The scaling law in the scrape-off-layer (SOL) plasma is discussed, and the influence of the cross-field thermal conductivity, kappa , is analysed. Analyses are done for the edge temperature, temperature fall-off length and the fluctuation level. The dependencies on the heating power, edge density and safety factor are investigated.
