    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:

    In addition, the following courses were given by faculty members (affiliated with the Association) to students, for education and training in fusion-related disciplines, in the frame of their University Curricula (hours per week per semester):

    • NTUA: Plasma Waves, 13  4 hours per semester (undergraduate),

    • NTUA: Beams and High-Power Microwaves, 13  4 hours per semester (undergraduate; focusing on the physics of fusion plasma heating devices),

    C5 2009 Co-operations and Mobility Missions

    Most of the work of the Research Unit of the Association is performed in collaboration with other Associations. This is facilitated both by the eligibility of this work for preferential support, under the provisions for “Projects for enhancing the mutual co-operation between Associations”, as well as by the Mobility scheme of the EURATOM Fusion Programme. During year 2009, the following missions were undertaken by personnel of the Research Unit:
