C1 9th School and Workshop on Fusion Physics and Technology

The Administrative Committee of the Research Unit of the Association and the University of Thessaly organised the “Nineth School and Workshop on Fusion Physics and Technology”, held in Volos from 19 to 23 April 2010. The School was again successful, in spite of the flight problems created by the Islandic volcano which resulted in the cancellation of some of the lectures. For budgetary reasons, the School lasted for 5 days, which were organised in 13 Sessions as follows: 1 Introductory session, 8 sessions for School Lectures, 4 Tutorial Sessions, and 4 Workshops. The lectures had been programmed to be given by 10 distinguished visiting scholars, while some of them have been cancelled (in alphabetical order: Buehler (cancelled), Haidemenopoulos, Hogge (cancelled), Kuiroukidis, Moradi, Pagonakis (cancelled), Papastergiou, Ram, Spatschek (cancelled), Weyssow (cancelled)), as well as by the scientific personnel of the Association. The audience consisted of graduate students and young scientists (mostly, affiliated with the Research Unit), as well as students interested in participating in fusion activities. In order of presentation, the following talks were given:
