New finding may explain heat loss in fusion reactors

One of the biggest obstacles to making fusion power practical—and realizing its promise of virtually limitless and relatively clean energy—has been that computer models have been unable to predict how the hot, electrically ...

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 ...

Upping the power triggers an ordered helical plasma

If you keep twisting a straight elastic string, at some moment it starts kinking in a wild way. Something similar occurs when one increases the electrical current flowing in a magnetized plasma doughnut: it takes on a wild ...

Signs of ideal surfing conditions spotted in ocean of solar wind

(PhysOrg.com) -- Researchers at the University of Warwick have found what could be the signal of ideal wave "surfing" conditions for individual particles within the massive turbulent ocean of the solar wind. The discovery ...

Radar gun catches predator shredding turbulence in fusion plasma

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 ...

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 ...

Scientists help solve mystery of why comets emit X-rays

The mystery of why comets travelling through Space give off X-ray emissions has been solved thanks to new research undertaken by a team that included science staff from STFC's Central Laser Facility (CLF) and RAL Space.
