Multiscale simulations help predict unruly plasma behavior

Decades of fusion research have brought many advances in our understanding of the physics of plasma, the hot ionized gas at the heart of a fusion reactor. While many questions are being answered, important challenges remain.

Table top plasma gets wind of solar turbulence

Scientists from India and Portugal recreated solar turbulence on a tabletop using a high intensity ultrashort laser pulse to excite a hot, dense plasma and followed the evolution of the giant magnetic field generated by the ...

Reading between the lines of highly turbulent plasmas

Plasma, the ionised state of matter found in stars, is still not fully understood, largely due to its instability. Astrophysicists have long sought to develop models that can account for the turbulent motions inside plasma, ...

Turbulent transport of hydrogen fuel in fusion plasmas

Using large-scale computer simulations, the Plasma Physics and Fusion Energy research group at the Department of Earth and Space Sciences is making important contributions to Joint European Torus (JET), the biggest fusion ...

A turbulent solution to a growing problem

A recent experiment lead by University of California, Los Angeles (UCLA), researchers on the DIII-D tokamak suggests that plasma turbulence can prevent filamentary structures called magnetic islands from growing so large ...

Multi-scale simulations solve a plasma turbulence mystery

Cutting-edge simulations run at Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center (NERSC) over a two-year period are helping physicists better understand what influences the behavior ...
