(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.

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.
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.
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:
The desired participants by application are young researchers at about the post-doc level working in the field of modelling and simulation of plasma-material interaction or of related materials processes and properties in connection with fusion energy research. Applications for participation are accepted through the ICTP webpage for this event. A scientific contribution (normally a poster, but some may be selected for a talk) is expected from each participant. Applicants are requested to attach a one-page abstract of their contribution in the Research Abstract subsection under Professional Data.
Here are links to pdf files for the Second Announcement of the School and Workshop (including local information) and of the final detailed agenda and programme.
Lectures, other presentations and computer training are all held in Room 601, 6th floor, Building No. 4, ASIPP. The posters are in the middle meeting room on that same floor starting on Tuesday with a dedicated poster session on Thursday afternoon.

Saturday 23 July 2016 / Departure |
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.
The present event has been advertised on several meetings lists (thank you!) and these lists may be a good source of information about many other events of related interest.
