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 ...

Hundred million degree fluid key to fusion

Scientists developing fusion energy experiments have solved a puzzle of why their million-degree heating beams sometimes fail, and instead destabilise the fusion experiments before energy is generated.

Abrupt excitation phenomenon in high-temperature plasma

At the National Institutes of Natural Sciences National Institute for Fusion Science, researchers have developed the high-energy heavy ion beam probe, in order to perform potential measurement inside a high-temperature plasma ...

Controlling ITER with fuelers, ticklers, and terminators

When it's up and running, the ITER fusion reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees centigrade. The systems that fuel and control it, on the other ...

Using radio waves to control the density in a fusion plasma

Recent fusion experiments on the DIII-D tokamak at General Atomics (San Diego) and the Alcator C-Mod tokamak at MIT (Cambridge, Massachusetts), show that beaming microwaves into the center of the plasma can be used to control ...

Carbon nanostructures grow under extreme particle bombardment

(Phys.org) —Nanostructures, such as graphene and carbon nanotubes, can develop under far extremer plasma conditions than was previously thought. Plasmas (hot, charged gases) are already widely used to produce interesting ...
