2016 Joint ICTP-CAS-IAEA School and Workshop on Plasma-Material Interaction in Fusion Devices

(The event has concluded. This web page serves as a record and it provides links to many of the presentations that were given in the school and workshop.)

The Abdus Salam International Centre for Theoretical Physics (ICTP), the Chinese Academy of Sciences (CAS) and the International Atomic Energy Agency (IAEA) will jointly organize this school and workshop to be held in Hefei, China, hosted by the CAS Institutes of Plasma Physics (ASIPP) and of Solid State Physics (ISSP), from 18 to 22 July 2016. The event will be devoted to computational methods and their application for the study of plasma-material interaction processes in fusion devices and of related material properties. The schedule will feature lectures by international experts, exposure to some important codes, invited and contributed research talks, posters and discussion sessions, with good time available for personal interaction. The event will be conducted in English and we expect participants from around the world.

BACKGROUND TO THE EVENT

The study of plasma-material interaction in fusion devices is devoted foremost to the twin topics of erosion and hydrogen (tritium) retention, and it is closely connected to the study of material microstructure and radiation damage. Basic computational methods include first-principles electronic structure calculations, classical molecular dynamics (MD), kinetic Monte Carlo (KMC) and rate equation modeling, quantum transition state theory, and path integral approaches to hydrogen and defect migration, among other methods. The field has a strong interest in predictive simulations and also in simulations to support interpretation of experimental data. Relevant research is carried out in fusion and materials research institutes and in university departments of physics, chemistry and engineering science.

China has a strong and rapidly developing programme of fusion energy research. The principal experimental facilities are the HL-2A tokamak at SWIP in Chengdu and the EAST superconducting tokamak at ASIPP in Hefei, and there is a diverse programme of fusion theory and experiment distributed over more than 10 universities. In addition China has its ITER domestic programme and a vigorous design effort towards a Chinese Fusion Engineering Test Reactor (CFETR) that is to be constructed in parallel with ITER. In connection with these facilities and with ITER construction and CFETR design there is in China a broad modelling effort for plasma-material interaction with interest in all relevant plasma-facing materials, from beryllium, carbon and tungsten to steel and liquid metals.

PURPOSE

The meeting will bring together researchers (lecturers, invited speakers and participants by application) from the areas of materials science and plasma-material interaction in connection with nuclear fusion. Participants should return from the meeting with a richer understanding of computational methods for study of plasma-material interaction processes and of the applications of these methods in fusion energy research.

The school and workshop is being held in China in order to take advantage of that country's rapidly growing expertise in modelling of fusion materials and plasma-material interaction and to promote interaction between younger Chinese scientists in particular and their international peers.

TOPICS

The school and workshop is devoted to computational methods and their application for the study of plasma-material interaction processes in fusion devices and of related material properties. Processes, methods and classes of simulations and data within the scope of the event include:

• Electronic structure methods and tools for study of material microstructure and trapping and transport of H and He in fusion wall materials.
• Development of classical interaction potentials for molecular dynamics (MD) studies.
• Development of rate coefficients for Kinetic Monte Carlo (KMC) and other long-time evolution calculations.
• Simulation methods for interpretation of experimental data, for example data obtained by thermal desorption spectroscopy.
• Specific computational studies of erosion of plasma-facing materials due to plasma exposure, of radiation damage in plasma-facing materials and of trapping and migration of hydrogen and helium in such materials.

RELATED MEETINGS

In 2014 the IAEA A+M Data Unit organized the Joint ICTP-IAEA Conference on Models and Data for Plasma-Material Interaction in Fusion Devices. The event in Hefei in 2016 will have a similar scope, but a stronger emphasis on training.

In 2015 the IAEA A+M Data Unit organized the Joint ICTP-IAEA Advanced School and Workshop on Modern Methods in Plasma Spectroscopy and in 2017 the Unit organized the Joint ICTP-IAEA School on Atomic Processes in Plasmas. The event in Hefei in 2016 will have a different scope, but a similar emphasis on training.

Another meeting with a similar scope is the (First) International Workshop on Models and Data for Plasma-Material Interaction in Fusion Devices (MoD-PMI 2015) that was held 25-27 May 2015 in Marseille, France. The Second International Workshop on Models and Data for Plasma-Material Interaction in Fusion Devices (MoD-PMI 2016) was held 22-24 June 2016 in Loughborough, UK.
