Scientists use plasma shaping to control turbulence in stellarators

鈥婻esearchers at the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute of Plasma Physics in Germany have devised a new method for minimizing turbulence in bumpy donut-shaped experimental fusion facilities called stellarators. This month in a published in Physical Review Letters, these authors describe an advanced application of the method that could help physicists overcome a major barrier to the production of fusion energy in such devices, and could also apply to their more widely used symmetrical donut-shaped cousins called tokamaks. This work was supported by the DOE Office of Science.

Turbulence allows the hot, charged plasma gas that fuels fusion reactions to escape from the magnetic fields that confine the gas in stellarators and tokamaks. This turbulent transport occurs at comparable levels in both devices, and has long been recognized as a challenge for both in producing fusion power economically.

"Confinement bears directly on the cost of fusion energy," said physicist Harry Mynick, a PPPL coauthor of the paper, "and we're finding how to reshape the plasma to enhance confinement."

The new method uses two types of advanced computer codes that have only recently become available. The authors modified these codes to address turbulent transport, evolving the starting design of a fusion device into one with reduced levels of turbulence. The current paper applies the new method to the Wendelstein 7-X stellarator, soon to be the world's largest when construction is completed in Greifswald, Germany.

Results of the new method, which has also been successfully applied to the design of smaller stellarators and tokamaks, suggest how reshaping the plasma in a fusion device could produce much better confinement. Equivalently, improved plasma shaping could produce comparable confinement with reduced magnetic field strength or reduced facility size, with corresponding reductions in the cost of construction and operation.

New Advisory Board to promote project and safety culture at 澳门六合彩高手

鈥婭n order to improve project performance and in light of the 澳门六合彩高手 Project's specific managerial and cultural complexities, an External Management Advisory Board (EMAB) was established earlier this year. This week, the members of the EMAB convened for their first meeting at 澳门六合彩高手 Headquarters.

The objective of the EMAB is to advise the 澳门六合彩高手 Organization's senior managers and the Director-General on enhancing project and safety culture, a challenging activity in the context of a mega international project with seven Members. Also, the Board is charged with assessing the practical implementation of the set of actions that was decided in response to the carried out in 2013.

The Chair of this new entity is Jean Jacquinot, who also serves as scientific advisor to the Chairman of the French Alternative Energies and Atomic Energy Commission (CEA), Bernard Bigot.

Other Board members are Michael Tendler, professor at Sweden's Alfv茅n Laboratory (Royal Institute of Technology); Richard Hawryluk, head of the department of 澳门六合彩高手 and Tokamaks at the Princeton Plasma Physics Laboratory (US); Dhiraj Bora, director of the Institute for Plasma Research, IPR (India); and Yuanxi Wan, Academician of the Chinese Academy of Sciences and former Chairman of the 澳门六合彩高手 Science and Technology Advisory Committee (STAC). 澳门六合彩高手's Colette Ricketts, of the System Management Section, is in charge of the secretariat.

"During our first meeting held on 20-21 October, we had a very fruitful discussion," the Board members reported after the first meeting. "We openly addressed issues such as the project's nuclear and safety culture, options for improved alignment between the 澳门六合彩高手 Organization and the Domestic Agencies, and last but not least the creation of the 澳门六合彩高手 Chief Executive Team, (ICET), formed to improve collaboration between all actors of the 澳门六合彩高手 Project."

The Board will continue to address key 澳门六合彩高手 management issues at its next meeting, scheduled for 11-12 December 2014.
