JET’s Final Tritium Experiments Yield Record Energy Output**\n- On April 8, 2026, the UK Atomic Energy Authority (UKAEA) announced the final results from the Joint European Torus (JET) reactor's last deuterium-tritium experiments, conducted in September 2023 before its decommissioning. Newly analyzed data revealed a total energy output of **69 megajoules over a 5.2-second pulse**, confirming sustained high performance. This result, published in *Nature Physics* (April 7, 2026), represents the highest total fusion energy yield from any tokamak to date and provides critical validation for ITER’s operational models.

Commonwealth Fusion Systems Achieves 10-Tesla Field in SPARC Assembly**\n\n## Analysis\nOn April 10, 2026, Commonwealth Fusion Systems (CFS) reported that the first full-scale toroidal field coil for its SPARC tokamak achieved a peak magnetic field of **10.2 tesla** during factory testing at MIT’s Plasma Science and Fusion Center. The high-temperature superconducting (HTS) magnet, cooled to 20 K, met all design specifications. CFS confirmed that assembly of the SPARC device at the Devens, Massachusetts site is 65% complete, with first plasma now projected for Q4 2026.

China’s EAST Sets New Pulse Duration Record**\n\nThe Experimental Advanced Superconducting Tokamak (EAST) at the Hefei Institutes of Physical Science achieved a **H-mode plasma pulse lasting 403 seconds** on April 6, 2026, under electron cyclotron resonance heating.
