UK's MAST Upgrade fusion machine gets its 12-tonne heating upgrade
From the Energy digest for Nov 4, 2026
What happened: Engineers at Britain's MAST Upgrade fusion machine in Oxfordshire moved a 12-tonne double beam box into position. The heating component is set to double the machine's plasma conditions, to 60 million degrees Celsius (108 million °F).
What's genuinely new: A concrete hardware step in the UK's fusion programme: the beam box is installed, turning a planned capability upgrade into physical reality ahead of heated-plasma operations.
Watch: First heated-plasma results against the doubling claim, the machine's experimental schedule, and how UKAEA's upgrade campaign feeds the UK's broader fusion ambitions.
