There are two major approaches in fusion energy research, Magnetic Fusion Energy (MFE) and Inertial Fusion Energy (IFE). The basic physics of IFE (compression and ignition of small fuel pellets containing deuterium and tritium) is becoming increasingly well understood. Based on recent advances by individual countries, IFE is now at the stage where large benefits can be obtained from a coordinated approach in the form of an IAEA Coordinated Research Project (CRP). This CRP will help Member States to promote the development of plasma/fusion technology transfer and to emphasize safety and environmental advantages of fusion energy. The CRP will document the state of art and conduct research to help resolve key issues on IFE research. The CRP will focus on interface issues including those related to 1) the driver/target interface (e.g., focusing and beam uniformity required by the target), 2) the driver/chamber interface (e.g., final optics and magnets protection and shielding), 3) and the target/chamber interface (e.g., target survival during injection, target positioning and tracking in chamber). This CRP will also include an assessment of the state of the art of the technologies required for an IFE power plant (drivers, chambers, targets) and systems integration and assessments of environmental, safety and economic (ESE) aspects.
