11th International Workshop on Plasma-Facing Materials and Components for Fusion Applications at the IPP Greifswald

The lecture hall in the Max Planck Institute in Greifswald was crowded like never before. Instead of the usual 80 participants, more than 155 researchers from 23 countries wanted to participate in the 11th International Workshop on Plasma-  Facing Materials and Components for Fusion Applications. Over the following three days, 64 posters were presented and 24 oral presentations given on the latest results in the fi eld of materials for fusion applications, such as tritium retention and requirements for removal techniques, transient heat loads in current fusion experiments, R & D improvements on tungsten materials and the manufacture of beryllium coatings.

Guy Matthews, responsible for the ITER-like Wall Project at JET, stressed the importance of the workshop: “We understand the problems better now. There is lot of good work presented here. Work on new materials, bonding, fatigue – all the related technology issues. The scale of it shows how relevant the topic is, now that ITER construction is immenent. It has grown by about a factor two since the last workshop and I think it puts emphasis on the fact that when building a big machine like ITER, all the technology issues become much more important than in the past, when people were more interested in plasma physics problems. Now we are really going to build the machine. The whole reliability of the fi rst wall, the water cooling, are fi rst and foremost in everyone´s mind. Certainly, it is these things that will determine more than anything else whether ITER is successful or not. Maintainability and reliability is going to be decisive if ITER is going to be a success.”
