    During the calendar year 1995 the national magnetic fusion program has undergone a dramatic change, redefining itself as being devoted to the scientific base of magnetic fusion, alternate concepts, ITER, collaborative research, basic plasma physics, and outreach. The work of the Magneto-Fluid Dynamics Division has consistently had such a range of activities, and expects to continue to carry out such a program. A sampling of major work of the last year includes
    1. Development of advanced algorithms and codes for three-dimensional magnetohydrodynamics. Applications to poloidal spin-up, ELM's, reversed shear stability studies. Collaboration with PPPL, DIII-D.
    2. Development of radiative, multispecies divertor codes. Applications to ASDEX-Upgrade, ITER. Collaborations with PPPL, IPP-Garching, KFA-Julich, Japan, Korea.
    3. Development of new, advanced statistical techniques for time series and profile analysis. Application to JET, DIII-D, earthquake predictability. Collaboration with JET, DIII-D, several groups outside the magnetic fusion program.
    4. Basic plasma physics studies of properties of the magnetic moment in nonsymmetric geometries, the form of the collision integral for non-smooth distribution functions, and the existence of explosive instabilities and a continuous spectrum. Collaborations with IPP-Garching.
    5. Transport and current drive studies. Alpha particle currents in reacting plasmas, and modifications possible by application of RF. Neoclassical transport in systems with large gradients. Ripple-induced transport. Collaborations with PPPL, Ecole Royale Militaire, Belgium; KFA-Julich, KAIST, Korea.
    6. Basic magnetohydrodynamics stability studies of the effects of sheared relation and of ballooning stability of supersonic flows.
    7. The Division was also active in sponsoring and organizing the Fifth International Plasma Edge Theory Meeting, and an interdisciplinary Workshop on Unstructured Mesh Methods in Fluids and Plasmas.

    Future Work [to top]

    Most of the work of the Division has obvious and natural extensions into the next year. The advanced MHD codes require further development and integration into the PPPL code structures before full implementation is possible. The edge physics codes are appropriate for application to a wide range of divertor studies, and a wide range of new physics results are likely. The transport studies have raised a wide range of issues, from large gradient effects, alpha particle effects, analytic theories of three-dimensional, low collisionality transport, to interpretation of present experimental results. Further development of edge and divertor analysis, magnetohydrodynamic stability, and basic atomic process is likely. The statistical analysis of existing databases and integration of results associated with diverse devices is also a significant part of our future plans. It is likely that work will be resumed on the theory of mode conversion in plasma waves, a subject not examined in this group for several years.

    The many natural and international collaborations will continue, but of special note is the role of C.S. Chang as an intermediary in the arrangements for the U.S.-Korea collaborations. He is firmly based in the U.S., but serves on many Korean committees planning the development of the Korean fusion program. He has been instrumental in arranging many of the personnel exchanges.

    In another direction B. Braams is expected to become the next chair of EXERSUG, and should function not only to enhance DOE computing capability, but make others aware of the strengths of computational fusion activities.
