Proton-ion collisions: Behind the scenes of a hybrid interaction

Protons to the right, ions to the left: the basic principle of proton-ion collisions at the LHC might seem straightforward. However, this is an almost unprecedented mode of collider operation, certainly unique at the energy ...

The radiation belt storm probes

(Phys.org)—Since the dawn of the Space Age, mission planners have tried to follow one simple but important rule: Stay out of the van Allen Belts. The two doughnut-shaped regions around Earth are filled with "killer electrons," ...

Laser research shows promise for cancer treatment

(Phys.org) -- Scientists at Los Alamos National Laboratory have observed for the first time how a laser penetrates dense, electron-rich plasma to generate ions. The process has applications for developing next generation ...

Elusive matter found to be abundant far above Earth

(PhysOrg.com) -- Cold plasma has been well-hidden. Space physicists have long lacked clues to how much of this electrically charged gas exists tens of thousands of miles above Earth and how the stuff may impact our planet's ...

The perfect liquid -- now even more perfect

Ultra hot quark-gluon-plasma, generated by heavy-ion collisions in particle accelerators, is supposed to be the "most perfect fluid" in the world. Previous theories imposed a limit on how "liquid" fluids can be. Recent results ...

I-mode powers up on alcator C-mod tokamak

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 ...

Feeling the heat: 30 tons of fine control for fusion plasmas

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 ...

Exoplanet aurora: An out-of-this-world sight

Earth's aurorae, or Northern and Southern Lights, provide a dazzling light show to people living in the polar regions. Shimmering curtains of green and red undulate across the sky like a living thing. New research shows that ...
