Significant opportunities exist for participating in exciting research at all levels on the DIII-D tokamak in San Diego. The DIII-D program is a national and international collaboration among ~90 institutions. Collaborators lead and manage elements of the program, generate ideas and innovations, lead experiments, build and operate diagnostics and equipment, analyze data, provide theory and modeling, and report and publish results. Graduate and undergraduate students also find opportunities for contributing to world-class fusion science.
The overall goal of the DIII-D program is to establish the scientific basis for the optimization of the tokamak approach to fusion energy. This includes specific emphases on enabling the success of ITER by providing physics solutions to key physics issues, developing the physics basis for steady-state operation in ITER and beyond, and advancing the fundamental understanding of fusion plasmas along a broad front. The DIII-D program will also continue to be a leader in the development of a scientific basis for steady-state high performance Advanced Tokamak scenarios in support of burning-plasma research.
DIII-D scientists are committed to addressing ITER research needs. Efforts in this area include pioneering work in control of both core and edge instabilities, experiments addressing tritium retention, validating safe rapid plasma shutdown methods, and testing and developing operating scenarios for ITER. Experiments in DIII-D this year will evaluate the effect of magnetic perturbations on plasma performance using an insertable module to simulate the perturbations resulting from planned ITER Test Blanket Modules.
The research program includes major elements of fusion science: transport, stability, energetic particles, heating and current drive, pedestal and boundary physics. A hallmark of the DIII-D program is its emphasis on model validation enabled by a world-leading diagnostic set. DIII-D actively participates in the International Tokamak Physics Activity (ITPA) and internationally coordinated multi-machine experiments.
Significant new capabilities were added to DIII-D during a Long Torus Opening (April 2010 through March 2011). These included 5MW of variable off-axis neutral beam injection and current drive, 36 new internal centerpost coils to explore 3D field effects, increased neutral beam power, increased ECH power for electron heating and current drive, and new core and edge diagnostics.
The DIII-D program welcomes new ideas for research, which can be submitted at any time. Experimental planning for 2014 will commence with a Research Opportunities Forum and will include an open competition for the Torkil Jensen Award for Innovative Experiments. Please contact the area leaders listed below for more detailed information.
