Atomic, molecular and plasma-material interaction processes play a crucial role in plasma physics and engineering for fusion energy. Sophisticated atomic and molecular data taking into account electronic and molecular excited states are needed for the simplest species, hydrogen and helium, in order to model plasma fuelling via neutral gas puff, neutral beam injection or pellet injection and to model helium exhaust from the divertor plasma. State-resolved data for collisional and radiative processes involving plasma impurities, including various hydrides and hydrocarbons, are needed in order to interpret spectroscopic measurements of impurities in near-wall plasma. Atomic impurities in the plasma may be in charge state and excited state population distribution very far from any equilibrium, for example due to charge exchange with neutral beams in the core plasma or because they are sputtered or deliberately introduced as neutral species into hot near-wall plasma. Modelling of plasma-wall interaction requires data for physical and chemical sputtering, particle reflection, particle trapping and particle transport in the material, all of which depends not only upon energy and angle of the incoming particle but also on surface temperature, composition and microstructure and possibly in a nonlinear way on the incoming flux density.
All these modelling needs are made more severe in connection with planning for ITER(www.iter.org). ITER needs to handle 150 MW of fusion-alpha and heating power in long-pulse divertor operation while exhausting helium ash and controlling impurity influx. ITER, under construction but with the plasma-facing components still in the final stage of design, demands accurate predictive modelling.
Fusion plasma modellers need data that are as near as possible complete over a wide range of conditions, including conditions far from equilibrium, and they require reasonable assessments of data uncertainties and data quality; i.e., they require evaluated and, where possible, recommended data for all relevant atomic, molecular and plasma-material interaction processes. In most cases data are required to a level of resolution that cannot be provided by experiment; for example cross-section data are required to be resolved with respect to excited states of incoming and outgoing particles. Therefore, theoretical and derived data are an essential part of the database and only certain integrated measured data are available to help assess the uncertainty.
The increased sophistication of plasma modelling and the increased demands for interpretive and predictive modelling explain why the available databases for atomic, molecular and plasma-material interaction data have greatly increased in complexity over the years and will continue to increase in complexity as new kinetic and state-resolved modelling tools are developed and brought into use. The increased complexity of the data demands new efforts in estimating data uncertainty, evaluating data quality, recommending best data and identifying most critical data lacunae.
The mission of the IAEA Nuclear Data Section in the field of nuclear fusion is to provide Member States with internationally validated and recommended data in the areas of atomic, molecular, plasma-material and materials structure data as well as fusion neutron and high-energy irradiation data. The Technical Meeting on Data Evaluation for Atomic, Molecular and Plasma-Material Interaction Processes in Fusion is organized in order to strengthen the international effort on data evaluation, including assessment of data uncertainty and recommendation of standard data.
The overall objective of the Joint IAEA-NFRI Technical Meeting on Data Evaluation for Atomic, Molecular and Plasma-Material Interaction Processes in Fusion is to contribute to the development of an evaluated and internationally recommended library of atomic, molecular and plasma-material interaction (A+M+PMI) data for use in fusion plasma modelling. Topics of discussion include:
The meeting will have a limited number of invited talks in conjunction with the .8th International Symposium on Standard Reference Data.. Further the meeting will have invited and contributed oral presentations and a poster session. It is expected that invited talks will be 40 minutes in length and contributed talks will be 20 minutes. An electronic projector connected to a PC with a slot for a USB flash drive or memory stick will be available for the presentations (PDF or Power Point).
In addition to the presentations there will be expert working sessions and discussion sessions dedicated to guidelines for data evaluation and coordination of data evaluation activities.
All persons wishing to participate in the meeting are required to send a completed Participation Form (Form A) and the Paper Submission Form (Form B), if applicable, to the competent national authority (e.g. the Ministry of Foreign Affairs or national atomic energy authority) or to one of the organizations invited to participate for subsequent electronic transmission to the IAEA (firstname.lastname@example.org). A participant will be accepted only if the Participation Form A is transmitted through the competent national authority of a Member State of the IAEA or by an organization invited to participate.
A participant will be accepted only if the Participation Form A is transmitted through the competent national authority of a Member State of the IAEA or by an organization invited to participate.For more information on the competent national authority of each country, please contact email@example.com
No registration fee is charged to participants.
As a general rule, the IAEA does not pay for participants' travel and living expenses. However, limited funds are available to help meet the cost of attendance of selected specialists, mainly from developing countries with low economic resources. If governments wish to apply for a grant on behalf of one of their specialists, they should address specific requests to the IAEA Scientific Secretary at the International Atomic Energy Agency to this effect. Governments should ensure that applications for grants:
a) are received by the IAEA before 15 May 2012
b) are accompanied by a duly completed and signed Grant Form C
c) are accompanied by a duly completed and signed Grant Form B and abstract.
Awards will be announced after 15 June 2012.
The working language of the meeting will be English. All communications, synopses and full papers must be sent to the IAEA in English.
The meeting will be held in the Daejeon Convention Centre (DCC). Detailed information on accommodation and other administrative details will be available on the meeting web page well in advance of the meeting. Detailed information on accommodation and other relevant matters will be sent directly to all designated participants approximately three months before the meeting.
Designated participants who require a visa to enter Korea should submit the necessary application to the nearest diplomatic or consular representative of Korea as soon as possible. The official letter of invitation from the IAEA usually serves to assist with visa arrangements. General assistance inquiries in this regard can be addressed to Mr Khalid Sheikh, firstname.lastname@example.org.
