A Gyrokinetic Moment Model of the Plasma Boundary in Fusion Devices

The overall performance of fusion devices, such as tokamaks, is strongly correlated to the phenomena that occur in the boundary region, the outer plasma region that faces the wall of the device. The boundary plays a crucial role in regulating the heat and ...

Projective multiscale time-integration for electrostatic particle-in-cell methods

Jan Sickmann Hesthaven, Paul Isaac Denis Louis Marie Cazeaux

The simulation of problems in kinetic plasma physics is often challenging due to strongly coupled phenomena across multiple scales. In this work, we propose a wavelet-based coarse-grained numerical scheme, based on the framework of Equation-Free Projective ...

Plasma cleaning of ITER first mirrors

Stefano Alberti, Ivo Furno

Nuclear fusion is an extremely attractive option for future generations to compete with the strong increase in energy consumption. Proper control of the fusion plasma is mandatory to reach the ambitious objectives set while preserving the machine's integri ...

Measurement of the Radial Profile of the Plasma Isotopic Composition in JET Plasmas Using Alfven Eigenmodes

Duccio Testa, Patrick Blanchard, Theodoros Panis

The measurement of the plasma isotopic composition is necessary in future burning plasma devices such as ITER and DEMO as a tool for optimizing the DT fusion performance. This paper reports on the results of experiments performed on the JET tokamak where T ...

Influence of diamond surface termination on thermal boundary conductance between Al and diamond

Christian Monachon, Ludger Weber

The effect of diamond surface treatment on the Thermal Boundary Conductance (TBC) between Al and diamond is investigated. The treatments consist in either of the following: exposition to a plasma of pure Ar, Ar:H and Ar:O, and HNO3:H2SO4 acid dip for vario ...

ELMS and strike point jumps

Duccio Testa, Richard Pitts

If an ELM is a peeling of flux surfaces from the plasma, due to a broken separatrix, current density is lost as well as particles and energy. The fast loss of a current-carrying plasma layer modifies the plasma equilibrium, leading to sudden shifts in the ...

Polymer microchips bonded by O2-plasma activation

Hubert Girault, Joël Stéphane Rossier, Nicolas Xanthopoulos

This paper presents a fabrication of polymer microchips with homogeneous material technique due to surface treatment by plasma before sealing. UV laser photoablation was used for fast prototyping of microstructures, and oxygen plasma was used as a surface ...
