Plasma Material Interactions news

Could replacing failed plasma-facing components in the wall of a fusion reactor ever be as easy as changing a light bulb? That was the ambitious idea behind a collaborative project between CCFE / UKAEA (UK), Sandia National Laboratories (USA) and DIFFER (Netherlands), when the group ran a proof of principle demonstration earlier this year.

ITER reactor wall material exposed in Magnum-PSI
On Wednesday 21 March, the research facility Magnum-PSI at DIFFER (Dutch Institute for Fundamental Energy Research) set a new world record for longest exposure of a material to the harsh plasma conditions in future fusion reactors. Magnum-PSI exposed tungsten wall components to the equivalent of a full year of high power fusion operations in the future ITER reactor, 50 times more than the previous record. The exposure took only 18 hours to complete and shows Magnum-PSI's unique capability to investigate how materials hold up under a sizeable part of their lifetime in ITER.

analytical force balance on a dust particle in plasma
The journal Physics of Plasmas has chosen the paper An analytical force balance model for dust particles with size up to several Debye lengths (Damien Aussems et al.) as editor's pick in its November 2017 issue. In the paper, Damien and colleagues detail the various forces that work on a dust grain in a plasma environment during its growth process, which enables them to explain phases in a dust particle's development.

Thomas Morgan to lead work package on Liquid Metal Divertors
The EUROfusion research consortium has appointed DIFFER group leader Dr. Thomas Morgan as the leader of its new work package on self-repairing liquid metal walls for the exhaust of future fusion reactors. In the first two years of this European research package, Morgan wants to build on the field's current foundation in physics with a more engineering-oriented approach.
