Fusion reactor that employs liquid metal shower

In a magnetic field confinement fusion reactor, we maintain the high-temperature plasma through the magnetic field lines by floating the plasma apart from a vessel. However, there forms inevitably a location where the plasma ...

Steering a fusion plasma toward stability

Plasmas in fusion-energy producing devices are gases heated to millions of degrees that can carry millions of amperes of current. These superhot plasmas must be kept away from material surfaces of the vacuum vessel that contains ...

Japanese researchers find new classes of electron orbits

Phenomena like solar flares and auroras are consequences of magnetic reconnection in the near-Earth space. These "magnetic reconnection" events are akin to magnetic explosions that accelerate particles as they rapidly change ...

Creating antimatter via lasers?

Dramatic advances in laser technologies are enabling novel studies to explore laser-matter interactions at ultrahigh intensity. By focusing high-power laser pulses, electric fields (of orders of magnitude greater than found ...

Spherical tokamak as model for next steps in fusion energy

Among the top puzzles in the development of fusion energy is the best shape for the magnetic facility—or "bottle"—that will provide the next steps in the development of fusion reactors. Leading candidates include spherical ...

Understanding nature's patterns with plasmas

Patterns abound in nature, from zebra stripes and leopard spots to honeycombs and bands of clouds. Somehow, these patterns form and organize all by themselves. To better understand how, researchers have now created a new ...

Detecting radioactive material from a remote distance

In 2004 British national Dhiren Barot was arrested for conspiring to commit a public nuisance by the use of radioactive materials, among other charges. Authorities claimed that Barot had researched the production of "dirty ...

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.
