JET’s Final Tritium Experiment Results Published (April 7, 2026)**\n- The UK Atomic Energy Authority (UKAEA) released the final scientific analysis from the Joint European Torus (JET) experiments conducted in October 2023, its last operational campaign. The paper, published in *Nature Physics* on April 7, 2026, confirmed a record total fusion energy output of 69 megajoules over a 5-second pulse using a deuterium-tritium mix, sustaining a power level of 13.8 MW. This final data set validates the reliability of JET’s plasma performance and provides critical benchmarking for ITER. The study underscores the effectiveness of the ITER-like tungsten divertor design.\n- Source: [https://www.nature.com/articles/s41567-026-02401-y](https://www.nature.com/articles/s41567-026-02401-y)\n\n## Analysis\n**2. Commonwealth Fusion Systems Achieves 8-Tesla Field in SPARC Magnet Array (April 10, 2026)**\n\nCommonwealth Fusion Systems (CFS) announced that its SPARC tokamak’s first full toroidal field magnet array achieved a peak magnetic field of 8.05 Tesla during integrated testing at its Devens, Massachusetts facility. This milestone marks the first time a high-temperature superconducting (HTS) magnet system has operated at full design field in a tokamak-relevant configuration. CFS confirmed that all six sector modules demonstrated stable performance under cryogenic conditions, a critical step toward SPARC’s planned first plasma in late 2027.\n\nSource: [https://cfs.energy/news/sparc-magnet-milestone-april2026](https://cfs.energy/news/sparc-magnet-milestone-april2026)\n\n## Sources\n- https://www.nature.com/articles/s41567-026-02401-y\n- https://cfs.energy/news/sparc-magnet-milestone-april2026\n- http://english.hf.cas.cn/news/2026-04-06/EAST_long_pulse_record/\n- https:","keywords":["zo-research","dynamic:fusion-energy"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
