The insides of nuclear fusion reactors are violent and chaotic places. A new cold-spray coating can take the heat and also trap some rogue hydrogen particles at the same time, potentially making for ...

The new material, created by spraying a tantalum coating on stainless steel, can withstand extreme conditions inside fusion reactors. This advancement enables more efficient fusion reactors that are ...

Experiments show fusion plasma can stay stable at higher densities by controlling reactor walls, challenging long-standing limits.

(Left) Measured and simulated electron temperature curves during an NBI pulse showing the outcome of the competing effects between neutral particle-derived fast ions and cold electrons. (Right) One of ...

Fusion energy, the process of fusing light atomic nuclei to generate energy, has long been considered the key to a clean and ...

In the quest for sustainable and limitless energy, fusion research has made significant strides, with the recent formation of stable plasma rings in laboratory settings marking a pivotal breakthrough.

A team of scientists has made a major breakthrough in fusion energy research that could bring us a step closer to limitless energy. The researchers, at the UK Atomic Energy Authority (UKAEA), have ...

Fusion energy is being developed as a solution to global energy problems. In particular, the magnetic confinement method, in which ultra-high temperature plasma is confined by a magnetic field, is the ...

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 ...

Some believe the future of fusion in the U.S. lies in compact, spherical fusion vessels. A smaller tokamak, it is thought, could offer a more economical fusion option. The trick is squeezing ...
