JET’s Final Results Confirm High-Triples Product in Deuterium-Tritium Plasmas**\n- On April 5, 2026, the UK Atomic Energy Authority (UKAEA) released the final scientific analysis from the Joint European Torus (JET), which concluded operations in December 2023. The peer-reviewed study, published in *Nature Physics*, confirmed that JET achieved a sustained fusion triple product of 1.7 × 10²¹ keV·s·m⁻³ during its 2021–2023 experimental campaign—the highest ever recorded in a tokamak. The results validated the use of ITER-like tungsten divertors and provided critical data for predicting performance in ITER.\n- Source: [UKAEA Press Release, April 5, 2026](https://www.gov.uk/ukaea-jet-final-results)\n\n## Analysis\nSource: *Nature Physics* (2026) DOI: 10.1038/s41567-026-0238-y\n\n**2. Commonwealth Fusion Systems Achieves 20 Tesla Field in New HTS Magnet**\n\nOn April 8, 2026, Commonwealth Fusion Systems (CFS) announced the successful test of its third-generation high-temperature superconducting (HTS) magnet at MIT’s Plasma Science and Fusion Center. The magnet achieved a peak field of 20.2 tesla, surpassing the 20 T threshold needed for compact tokamak designs. This milestone supports the ongoing construction of SPARC, which is now 68% complete and on track for first plasma in Q4 2027.\n\n## Sources\n- https://www.gov.uk/ukaea-jet-final-results\n- https://cfs.energy/news/sparc-magnet-milestone-april2026\n- https://www.iter.org/newsline/-/3452\n- https://tae.tech/news/copernicus-milestone-april2026\n\n## Implications\n- This milestone supports the ongoing construction of SPARC, which is now 68% complete and on track for first plasma in Q4 2027","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"}}
