PPPL presented its 2013 outstanding research awards to physicists Steven Sabbagh and Gregory Hammett following Director Stewart Prager’s May 28 State-of-the-Laboratory Address. Sabbagh received the Kaul Foundation Prize for Excellence in Plasma Physics Research and Technology Development for his work on advancing the understanding, and enhancing the stability, of high-performance plasmas in fusion facilities called tokamaks. Hammett was named winner of the Distinguished Research Fellow Award for his work on deepening the theoretical understanding of turbulence in fusion plasmas.
ITER is a large international fusion experiment aimed at demonstrating the scientific and technological feasibility of fusion energy.
ITER (Latin for "the way") will play a critical role advancing the worldwide availability of energy from fusion — the power source of the sun and the stars.
To produce practical amounts of fusion power on earth, heavy forms of hydrogen are joined together at high temperature with an accompanying production of heat energy. The fuel must be held at a temperature of over 100 million degrees Celsius. At these high temperatures, the electrons are detached from the nuclei of the atoms, in a state of matter called plasma.
Phil Heitzenroeder, who leads the Mechanical Engineering Division at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and whose advice is sought by engineers around the world, has won the 2013 Fusion Technology Award. The high honor from the Nuclear and Plasma Sciences Society of the Institute of Electrical and Electronics Engineers (IEEE) recognizes outstanding contributions to research and development in the field of fusion technology.
What is it like to be at the center of ITER, the huge international fusion experiment that is under construction in Cadarache, France? “It’s both exciting and challenging,” said physicist Rich Hawryluk, who recently returned to PPPL after a two-year stint as deputy director-general for the Administration Department of ITER. “It’s exciting in the scope and scale of this effort, and challenging in bringing such a large project to completion.”
Mark your calendar and prepare to have some fun at The Princeton Plasma Physics Lab's Open House on June 1 from 9 a.m. to 4 p.m. when the Laboratory will open its doors for the public to see the National Spherical Torus Experiment and other research experiments. Come take a self-guided tour, take part in hands-on activities, watch demonstrations. Plans also include a moon rocks display from NASA, lectures on fusion by PPPL Director Stewart Prager, a cryogenics show, firefighting demonstrations and numerous other activities as well as refreshments and give-aways.
When the ITER experimental fusion reactor begins operation in the 2020s, over 40 diagnostic tools will provide essential data to researchers seeking to understand plasma behavior and optimize fusion performance. But before the ITER tokamak is built, researchers need to determine an efficient way of fitting all of these tools into a limited number of shielded ports that will protect the delicate diagnostic hardware and other parts of the machine from neutron flux and intense heat.
Scientists participating in the worldwide effort to develop magnetic fusion energy for generating electricity gave progress reports to the 2013 annual meeting of the American Association for the Advancement of Science in Boston. Speaking were physicists George "Hutch" Neilson of the U.S. Department of Energy's Princeton Plasma Physics Laboratory, and Richard Hawryluk, deputy director-general of the ITER Organization. Following are summaries of their presentations.
Previewing the next steps on the path to a magnetic fusion power plant

Physicist John Schmidt, whose profound and wide-ranging contributions to the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) made him a highly respected leader in the worldwide quest for fusion energy, died on February 13 following a brain hemorrhage. He was 72.
Three teams led by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have won major blocks of time on two of the world’s most powerful supercomputers. Two of the projects seek to advance the development of nuclear fusion as a clean and abundant source of energy by improving understanding of the superhot, electrically charged plasma gas that fuels fusion reactions.
