Scientists develop new tool to design better fusion devices

One way that scientists seek to bring to Earth the fusion process that powers the sun and stars is trapping hot, charged plasma gas within a twisting magnetic coil device shaped like a breakfast cruller. But the device, called ...

Imaging magnetic instabilities using laser accelerated protons

The magnetic structures resulting from a plasma instability predicted by the physicist Erich Weibel about 50 years ago have been evidenced at surprisingly large scales in a laser-driven plasma in the prestigious journal Nature ...

Improved understanding of the behavior of electrons in plasmas

Plasmas are strongly associated with thermonuclear reactions inside stars such as the sun, but in modern society, plasmas have found application in lithographic processes and decontamination techniques. High-temperature plasmas, ...

Topological waves may help in understanding plasma systems

Nearly 50 years ago, Brown University physicist Michael Kosterlitz and his colleagues used the mathematics of topology—the study of how objects can be deformed by stretching or twisting but not tearing or breaking—to ...

The exceptional origin of EUV light in hot tin plasma

Extreme ultraviolet light (EUV light) does not naturally occur on Earth, but it can be produced. In nanolithography machines, EUV light is generated using an immensely hot tin plasma. Researchers at ARCNL, in close collaboration ...

Fossil fuel-free jet propulsion with air plasmas

Humans depend on fossil fuels as their primary energy source, especially in transportation. However, fossil fuels are both unsustainable and unsafe, serving as the largest source of greenhouse gas emissions and leading to ...
