UK's latest nuclear fusion device generates its 1st plasma
The UK's newest nuclear fusion device has been turned on and has officially achieved first plasma (hot ionised gas). The ST40 spherical tokamak aims to produce temperatures of 100 million ÂºC, seven times hotter than Sun's core, necessary for a controlled fusion reaction. Tokamak Energy, a privately-funded venture, has set a goal to generate first fusion-powered electricity by 2025.
