The physical concept of the density-free regime has been verified for the first time on EAST in this work. The EAST experiments combine control of the initial fuel gas pressure with electron cyclotron ...

Scientists have used a pair of lasers and a supersonic sheet of gas to accelerate electrons to high energies in less than a ...

China’s latest advance with its so‑called artificial sun has pushed fusion plasma into a regime many physicists long treated as off limits, smashing through a density ceiling that had constrained ...

A team of U.S. scientists has made a surprising discovery that could help bring fusion energy, a long-hoped-for clean energy source, closer to reality. In a recent experiment at the University of ...

The interiors of fusion reactors can get seriously chaotic. But for obvious reasons—like extreme temperatures and pressures—researchers aren’t typically able to peek directly inside a reactor. Some ...

Experts at the BELLA Center used dual laser beams focused onto a sheet of gas to reach a milestone energy in laser-driven electron acceleration. Four members of the larger team gathered with the ...
