Plasma-wall interaction in flashtubes

Journal of Physics D: Applied Physics, 1979
A quasi-stationary arc has been established in a flashtube filled with a rare gas. The current intensity was varied in the range 1-3 kA and the arc lasted about 1 ms. The plasma parameters were determined spectroscopically and are typically Ne approximately 1018 cm-3 and T approximately 1 eV. This allows the study of non-ideal plasma effects.

Plasma-Wall Interaction Facilities in Korea

Fusion Science and Technology, 2013
Although the research of plasma-material interaction (PMI) is rather immature comparing the recent success of Korean fusion program, there are several facilities and programs of PMI research in Kor...

Plasma wall interactions in ITER

Physica Scripta, 2006
Designing the interface between a thermonuclear plasma and the solid material environment is arguably one of the highest technical challenges of ITER and of the successful development of future fusion power reactors. Carbon-based materials are recognized to have superior thermomechanical properties and do not melt, but they retain high levels of ...

Plasma–wall interaction issues in ITER

Journal of Nuclear Materials, 2001
Abstract In 1998 the four ITER parties decided to investigate a smaller and cheaper (50% cost) machine design with reduced technical objective but without jeopardizing the programmatic objective. Based on various design studies a machine with 6.2 m major radius and aspect ratio 3.1 has been selected.

Tritium issues in plasma wall interactions

AIP Conference Proceedings, 2010
Since tritium resources are very limited, not only for safety reason but also for tritium economy, tritium inventory in a reactor must be kept as small as possible. In the present tokamaks, however, hydrogen retention rate in their vacuum vessel is significantly large, i.e.

Models of Plasma Wall Interactions

1991
Impurity control is a major issue for controlled fusion research. The leading concept for obtaining the conditions for controlled fusion (using magnetic fields) is the tokamak. This paper will discuss models for impurity control in the context of applications for the tokamak. The fusion reaction (e.g.

Erosion processes in plasma-wall interactions

Journal of Nuclear Materials, 1994
During plasma-wall interactions in fusion experiments large energy and particle fluxes are deposited predominantly onto limiter and divertor structures. Besides good thermomechanical properties, plasma facing materials must exhibit low erosion yields.

Dynamic Models for Plasma‐Wall Interactions

Contributions to Plasma Physics, 2012
AbstractIn theory and modeling of plasma‐wall interactions, very different spatial and temporal scales need to be resolved. Hierarchy of material models (e.g. macroscopic transport, Kinetic Monte Carlo, Molecular Dynamics, and quantum models) used in fusion applications is reviewed and a way of their integration is highlighted.

Plasma-wall interactions in the TFR machine

Journal of Nuclear Materials, 1974
Abstract Experiments with the tokamak machine, TFR, operating up to 200 kA with 40 kG, have been stopped because the vacuum vessel broke suddenly during a pulse. Three kinds of damages have been observed: heat erosion of the limiter, deposition of eroded materials around the vacuum vessel and regularly spaced impacts on the vacuum vessel.
