C1 6th 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 “Sixth School and Workshop on Fusion Physics and Technology”, held in Volos from 26 to 31 March 2007. Following the trend established during the previous years, this year’s School surpassed in success the previous ones. This time it lasted 6 days, to accommodate the large number of presentations, which were organised in 14 Sessions, of which 2 were Plenary, 5 for Fusion School, 4 as Workshop Sessions, 2 as Research Seminars and, last but not least, one full-day Colloquium on Gyrotrons. The lectures were given by 19 distinguished visiting scholars (in alphabetical order: Bühler, Bruhns, Carati, Constantinescu, Dammertz, Fuhr, Giruzzi, Hartmann, Hogge, Papastergiou, Peysson, Petrisor, Pometescu, Prinz, Ram, Thumm, Watkins, Weyssow, Zurita), 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:
