News from the 53rd Annual Meeting of the APS Division of Plasma Physics Recent experiments carried out at the DIII-D tokamak in San Diego have allowed scientists to observe how fusion plasmas spontaneously turn off the plasma turbulence responsible for most of the heat loss in plasmas confined by toroidal magnetic fields. Using a new microwave instrument based on the same principles as police radar guns, researchers from UCLA observed the complex interplay between plasma turbulence and...

News from the 53rd Annual Meeting of the APS Division of Plasma Physics A key challenge in producing fusion energy is confining the plasma long enough for the ionized hydrogen to fuse and produce net power. Suppressing plasma turbulence is one approach to this, but the resulting increase in energy confinement is usually accompanied by undesirable increases in particle and impurity confinement, which can lead to plasma contamination and ash accumulation–and reduced power. At MIT's...

News from the 53rd Annual Meeting of the APS Division of Plasma Physics Tokamaks–a leading design concept for producing nuclear fusion energy–can, under certain rare fault conditions, produce beams of very energetic "runaway" electrons that have the potential to damage interior surfaces of the device. In the event of such a fault, a tokamak-based nuclear fusion power plant will have to employ protection systems to prevent any damage. Now, scientists at the DIII-D National...

News from the 53rd Annual Meeting of the APS Division of Plasma Physics A major upgrade to the DIII-D tokamak fusion reactor operated by General Atomics in San Diego will enable it to develop fusion plasmas that can burn indefinitely. Researchers installed a movable, 30-ton particle-beam heating system that drives electric current over a broad cross section of the magnetically confined plasma inside the reactor's vacuum vessel. Precise aiming of this beamline allows scientists to vary the...

An instrument developed by researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has enabled a research team at a fusion energy experiment in China to observe--in startling detail--how a particular type of electromagnetic wave known as a radiofrequency (RF) wave affects the behavior of hot ionized gas.  In the experiment at EAST (the Experimental Advanced Superconducting Tokamak located at the Institute of Plasma Physics in Hefei, China), scientists...

Key insight may help nuclear industry advance clean fusion power A new discovery about the dynamic impact of individual energetic particles into a solid surface improves our ability to predict surface stability or instability of materials under irradiation over time. The finding may lead to the design of improved structural materials for nuclear fission and fusion power plants, which must withstand constant irradiation over decades. It may also accelerate the advent of fusion power, which...

BARCELONA, Spain, Feb. 18, 2011 /PRNewswire/ -- Grifols, the Spanish group which specializes in the hospital-pharmaceutical sector and is one of the world's leading producers of plasma products, will shortly start construction of a new plant representing an investment of 20 million euros that will employ about 100 people, as soon as it obtains local permits and licenses. The new facilities will have the capacity to fractionate 1 million liters of plasma a year (with potential to expand...

Oak Ridge National Laboratory researchers Jeremy Busby, De-en Jiang and Sergei Kalinin are among 13 Department of Energy scientists to receive the Presidential Early Career Award for Scientists and Engineers, or PECASE. The PECASE, one of the nation's top honors for young scientists, was designed to recognize some of the finest researchers who show exceptional potential for leadership at the frontiers of scientific knowledge. "Science and technology have long been at the core of America's...

News from the 52nd annual meeting of the APS Division of Plasma Physics Fusion plasmas in the laboratory typically reach 100 million degrees. These high temperatures are required to ignite the hydrogen plasma and maintain the fusion burn by the production of high-energy alpha particles. One challenge for a fusion reactor is how to contain the alpha particles in the vessel long enough for the particles to efficiently heat the hydrogen plasma. One way that these alpha particles can escape the...

A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results. The findings confirm that its unique approach has some potential to be developed as a new way of creating a power-producing plant based on nuclear fusion "” the process that generates the sun's prodigious output of energy. Fusion has been a cherished goal of physicists and energy researchers for more than 50 years. That's because it offers the possibility of...
