World’s largest nuclear fusion research project ITER has reached a new milestone

Its first Japanese gyrotron is now in place and prepared for commissioning.

Gyrotrons are powerful RF generators that produce microwaves at 170 GHz—each delivering up to 1 MW of power.

These beams will heat ITER’s plasma to fusion conditions and help control instabilities.

In total, ITER will host 72 gyrotrons: 48 for the Start of Research Operations

Fusion is a process that powers Sun and other stars.

Controlled nuclear fusion can deliver limitless clean energy for humanity.
