International fusion community mobilized behind the WEST research plan

From 30 June to 2nd July 2014, the first WEST international workshop gathered 120 participants in Aix en Provence. The purpose was to consolidate the WEST research plan, that will drive WEST during the coming years. The target was reached: a revised version of the WEST research plan will be issued by the end of 2014, enriched by a number of new proposals. In parallel, the workshop conclusions form the basis of the future participation of the European fusion programme in WEST.


The 1st WEST International Workshop was held from 30 June to 2 July, in Aix en Provence, at the Aix Marseille University which co-organized the workshop, and at Cadarache for the last day with a visit of WEST and ITER worksites. This workshop was supported by the “Communauté du Pays d’Aix” who offered the beautiful Granet Museum premises for the Welcome Reception. Around 120 people from across the world were presents. The objective of these three days meeting was for the participants to contribute to the WEST scientific program. International fusion experts chaired discussions along topical headlines.


The meeting started with the requests of ITER Organization and domestic agencies in charge of procuring the ITER divertor targets. The EUROfusion representative introduced how WEST will be inserted as a new facility within the European fusion programme. General presentations of the WEST project by the IRFM team followed. The second day was devoted to parallel working sessions along topical headlines. The first addressing the start-up phase raised open issues on wall conditioning and radiofrequency plasma heating in full tungsten device. The second session dedicated to the testing of ITER tungsten plasma facing component, main purpose of the WEST project, highlighted the specificities of the actively cooled tokamak and the importance of running an helium campaign, in preparation of ITER non activated phase. The session on long pulse H-mode operation pointed out the interest of a high aspect ratio device in the understanding of turbulent transport. The session on exploring high particle fluence interrogated the behavior of components subjected to millions of small transients and the last one related to advanced tokamak modes brought-up the potential contributions to JT-60SA and ITER steady-state operation phase.

These discussions were very fruitful and summarized by the chairs of the working sessions on the 2nd of July. All of these outputs will be integrated to update the WEST research plan by end 2014.
