Scientific scope and aims
The International Workshop on Models and Data for Plasma-Material Interaction in Fusion Devices (MoD-PMI 2019) is organized in cooperation with the International Atomic Energy Agency (IAEA) for the fourth time. This workshop was initiated by the ICTP-IAEA Conference on MoD-PMI held in Trieste in 2014. Following the ICTP event, the first workshop on MoD-PMI was held in Marseille (2015), the 2nd workshop in Loughborough (2016), and the 3rd workshop in Jülich (2017).
The workshop is intended to bring together researchers from the areas of fusion energy and materials science to review advances, both experimental and in the modelling, in study and understanding of processes relevant to plasma-material interaction in fusion devices.
The workshop aims to provide a bridge between fundamental and multi-scale computations and interpretation of experimental data. A variety of processes to be addressed spans a wide range of scales and includes material erosion, transport and trapping of hydrogen and helium in fusion relevant materials, as well as changes in the material microstructure, composition and morphology.
MoD-PMI will cover all topics on advances in computational and experimental studies related to PMI processes and microstructural evolution of fusion relevant materials. Specific topics include the following:
