The WEST tokamak just broke the record for retaining hot fusion plasma, holding on to it for an unprecedented 22 minutes. WEST and other tokamaks are paving the way for ITER which, upon completion ...

The Sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are called coronal mass ejections, or CMEs. When two of these ejections ...

WEST sustained hydrogen plasma for over 20 minutes using 2 MW heating, marking a key milestone as experiments move to higher power.

Reaching durations such as these is a crucial milestone for machines like ITER, which will need to maintain fusion plasmas for several minutes. The end goal is to control the plasma, which is ...

The end goal is to control the plasma, which is naturally unstable, while ensuring that all plasma-facing components are able to withstand its radiation without malfunctioning or polluting it.

Feb. 18, 2025 — French research organization CEA reported that on 12 February, the CEA’s WEST tokamak maintained a nuclear fusion plasma for more than 22 minutes, a 25 percent improvement over the ...
