Seeing all the colors of the plasma wind

When it comes to plasma winds in a tokamak, researchers are always looking for the Goldilocks solution—one that is just right. Winds that are too high or too low can reduce plasma efficiency. Researchers at the DIII-D National ...

Spinning data into sound

It could be the background soundtrack for a science fiction movie. Some sounds bubble up like prehistoric chirps from primordial ooze. Others whirl up and down octaves, quickly joined by a progressive rattling that slinks ...

Why nuclear fusion is gaining steam – again

Back when I studied geology in grad school, the long-term future of energy had a single name: nuclear fusion. It was the 1970s. The physicists I studied with predicted that tapping this clean new source of electric power ...

Powerful new device for studying puzzling process

A millisecond burst of light on a computer monitor signaled production of the first plasma in a powerful new device for advancing research into magnetic reconnection—a critical but little understood process that occurs ...

Recreating outer space plasma systems in the lab

Thermodynamics provides insight into the internal energy of a system and the energy interaction with its surroundings. This relies on the local thermal equilibrium of a system. The application of classical thermodynamics ...

Upscaling turbulence for better laboratory studies

Turbulence in oceans, in the atmosphere or in industry is billions of times stronger than in lab experiments. Simply upscaling the lab results is not an option. Theoretically, however, there is a regime of turbulence in which ...

Superconducting tokamaks are standing tall

A persistent problem has dogged the largest fusion device in South Korea. The Korean Superconducting Tokamak Advanced Research (KSTAR) device has run successfully since 2008. However, controlling the vertical position of ...
