Technical Meeting on Plasma Physics and Technology Aspects of the Tritium Fuel Cycle for Fusion Energy

Topics

The programme will mainly consist of sessions dedicated to invited oral talks and poster presentations and discussions.

A Programme Committee made up of a representative international membership will be responsible for selecting the invited oral and poster presentations and arranging the technical and discussion sessions, as well as for the overall scientific content of the event.

The topical area of focus in this technical meeting series is the complex interface of plasma physics and the DT fuel cycle, a scope largely neglected by other major international meetings but having potentially large impacts on the operations and feasibility of fusion as an energy source.

Below is a representation of topical scope that will be addressed, and subsequent meetings may pursue other topics identified in deliberations or more deeply into any one of those.
