UK-based Tokamak Energy is developing new laser measurement technology to control extreme conditions inside future fusion power. Plasma temperatures inside a tokamak reach over 100m degrees Celsius. The hydrogen fuel must be closely and accurately measured by a specialist laser system to keep the hot plasma stable, hold density and maintain fusion conditions.

The first thermonuclear plasma has been achieved at the T-15MD tokamak, at Russia’s Kurchatov Institute and the facility is operating steadily, according to Kurchative Institute President Mikhail Kovalchuk. The physical launch of the T-15MD tokamak took place in May 2021. "The stable plasma, at millions of degrees Celsius, has been obtained.… This most complicated and expensive installation started up immediately and is now working, gaining power and reaching global parameters,” he said.

A Chinese tokamak device has set a new world record for a steady-state high-constraint mode plasma operation and German researchers have discovered a way to build smaller and cheaper fusion reactors. Meanwhile a US Government Accountability Office report on achieving commercial fusion cautions that several challenges must still be overcome.

Physicists at the Princeton Plasma Physics Laboratory (PPPL) have proposed that the formation of "hills and valleys" in magnetic field lines could be the source of sudden collapses of heat ahead of disruptions that can damage doughnut-shaped tokamak fusion facilities. Their discovery could help overcome a critical challenge facing such facilities.
