JET's DTE1 campaign sets the first deuterium-tritium fusion power record
In its first full deuterium-tritium campaign, JET reached a peak fusion power of 16.1 MW and produced 22 MJ of fusion energy in a single pulse of about six seconds, with roughly 675 MJ of fusion energy produced across the whole campaign. The ratio of fusion power to input heating power is commonly quoted at Q ≈ 0.62, with 0.67 also reported; both refer to a transient peak, and quasi-steady values were lower. JET consumed considerably more energy than it released, and produced no electricity.
Historical — it happened, and the record is settled.
