  1. Topic IV: Theory and modelling

  2. 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

  3. Topic IV: Theory and modelling • 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 • ‘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?
