Commonwealth Fusion Systems (CFS) Achieves First Plasma in SPARC Tokamak**\n- Commonwealth Fusion Systems, in collaboration with MIT, announced on March 28, 2026, that its SPARC tokamak achieved first plasma at its Devens, Massachusetts facility. SPARC, a compact high-field tokamak utilizing high-temperature superconducting (HTS) magnets, is designed to reach net energy gain (Q > 1) by late 2026. The successful plasma initiation marks a critical milestone toward demonstrating fusion as a viable energy source. SPARC aims to produce around 50–100 MW of fusion power.\n- Source: https://cfs.energy/news/sparc-first-plasma\n- b. Joint European Torus (JET) Final Results Confirm Tritium Efficiency**\n\n## Analysis\nThe UK Atomic Energy Authority released final scientific results from the decommissioned JET reactor in February 2026. Data from its final deuterium-tritium campaigns in 2023–2024 confirmed sustained fusion power of 69 MJ over 5 seconds, with improved tritium fuel retention management. These findings are critical for informing the operation of ITER and future commercial fusion plants.\n\nSource: https://www.ccfe.ukaea.uk/jet-final-results-2026/\n\n**c.
