CHAPTER C  Other Activities in 2009
C1 8th 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 “Eighth School and Workshop on Fusion Physics and Technology”, held in Volos from 6 to 11 April 2009. Following the trend established during the previous years, this year’s School surpassed in success the previous ones. In spite of the effort to reduce its duration (for fiscal reasons), it had again to last for 6 days, to accommodate the large number of presentations, which were organised in 14 Sessions, of which 2 were Plenary, 5 for Fusion School, 2 as Workshops, 1 as Tutorial Session, and 4 as Research Seminars. The lectures were given by 6 distinguished visiting scholars (in alphabetical order: Bartlett, Hogge, Peeters, Pagonakis, Ram, Weyssow), 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:
