G. De Temmerman 2nd PMIF workshop, Juelich, September 2011

Topic IV: Theory and modelling

3 main lines presented here: Support of PMI experiments in linear devices (ERO, transient heat

loads)

Understanding of plasma in a linear device

Design and optimization of future devices

PMI modelling: Aim of linear devices is to support research in confinement devices

Modelling aims at pin-pointing the basic mechanisms of PMI and put them in context of future devices

Important to gain understanding on the plasma physics/chemistry

Strong link is necessary

G. De Temmerman 2nd PMIF workshop, Juelich, September 2011

Modelling of linear plasma devices Impressive progress in adapting codes to linear devices (B2.5-Eirene

for example)

A linear plasma device is not so quiescent…

Important to assess the role of fluctuations (and timescales) on the spectroscopy measurements for example

Topic IV: Theory and modelling

‘Predictive modelling’ Increased complexity of newly proposed devices

Modelling necessary to design the device and optimize performances

Q: How do we ensure that modelling of linear plasma devices feed back on tokamak experiments?
