Two British public sector entities - the UK Atomic Energy Authority and the Science and Technology Facilities Council's Hartree Centre - have teamed up with US-headquartered technology firm IBM to design future experimental fusion power plants.

Scientists at the UK Atomic Energy Authority and Bristol University have created what they say is the world's first carbon-14 diamond battery, which has the potential to power devices for thousands of years.

The preliminary design of Russia's proposed TRT tokamak nuclear fusion reactor has been completed by JSC NIIEFA.

The energy departments of the US and UK governments are to partner with Tokamak Energy for a USD52 million upgrade of the ST40 fusion facility, which will coat its inner wall with lithium.

Focused Energy has completed a scientific report detailing its initial high-gain target design based on direct-drive laser inertial fusion, the first of its Milestones in the US Department of Energy's Milestone-based Fusion Development Program. 

A consortium of Assystem, Egis and Empresarios Agrupados has signed a contract with Fusion for Energy worth an initial EUR80 million (USD84 million) to provide consulting and engineering expertise on the ITER international fusion project.

The FAST (Fusion by Advanced Superconducting Tokamak) project has been launched in Japan with the aim of achieving fusion-based power generation by the end of the 2030s.

Leadership of the UK's STEP (Spherical Tokamak for Energy Production) programme has transitioned to UK Industrial Fusion Solutions Ltd, a wholly-owned subsidiary of the UK Atomic Energy Authority.

Developed in collaboration with the Max Planck Institute for Plasma Physics specifically for the Wendelstein 7-X stellarator, Thales's TH1507U gyrotron has achieved a significant milestone by reaching a total output of 1.3 megawatts in radiofrequency at a frequency of 140 gigahertz for 360 seconds.
