    Recent topics on fusion plasma heating are reviewed in concerned with the physics of lower hybrid wave heating and RF heating technology. Lower hybrid electron heating has a possibility to realize a high temperature and a stable current driven plasma without deterioration of confinement. The RF heating technology is based on the broad-casting technology, however, many renewed R&D are necessary to realize the reliable RF Heating system as an energy industry.

    Basic neutron behavior in the fusion reactor blanket and shield materials has been described using the terms of neutron moderation, diffusion, penetration and reflection. Special attention has been paid to explain the tritium breeding mechanism by the fusion neutrons in the blanket system. Status reviews on the neutron transport calculation techniques and relating researches to assess their accuracies have been also made.

    An overview is presented on the structural materials in fusion reactors such as the first wall/blanket structural materials, the divertor and limiter plate materials and the tritium breeding materials. Special emphasis is placed on the heavy irradiation effects on the blanket structural materials. The problem and the fundamental mechanisms of the irradiation effects and the current candidate materials are reviewed. A future strategy for the irradiation simulation studies is also presented.

  • Studies on the Formation Process and the Stability Properties of the Double-Spheromak Configuration in a Cusp Shaped Magnetic Field
    Yasushi Ono, Kozo Katayama, Akira Yumoto, Makoto Katsurai

    Computer analyses and preliminary experiments are carried out to investigate the formation process and the stability problems of double-spheromak configurations in a cusp-shaped magnetic field. For the finite-beta and nondynamical plasmas, 3-D MHD simulation shows the existence of the tilt and shift motions whose growth rate depends on the beta value and curvature of the separatrix surface. Formations of the configuration by the zeta-theta-pinch method are simulated by 2-D axisymmetric MHD code. During the formation period, a fluid velocity of about 0.3 Alfven speed is generated. This formation scheme is experimentally investigated with the TODAI spheromak producing machine, TS-3. The life time of produced plasmas is about 30 μs. During this period, no global instabilities are observed; however, complete stabilization is yet to be investigated.
