This marks the beginning of operational testing for the world’s largest tokamak, designed to demonstrate the feasibility of sustained deuterium-tritium fusion. Initial low-power tests are underway, with full-power experiments expected by 2030.  \n   - **Source:** [ITER Official Website – First Plasma Announcement](https://www.iter.org/firstplasma2026)\n\n2. **Commonwealth Fusion Systems (CFS) Demonstrates ARC Reactor Prototype**  \n   CFS, an MIT spinout, completed a full-scale test of its high-temperature superconducting (HTS) magnet system for the ARC (Affordable, Robust, Compact) reactor. The magnet achieved a field strength of 23 tesla, a record for fusion applications, enabling more compact reactor designs. Construction of the SPARC tokamak is on track for net energy gain (Q > 1) by late 2026.  \n   - **Source:** [CFS Press Release – March 2026](https://cfs.energy/news/sparc-magnet-milestone)\n\n3. **UK’s JET Concludes Operations with Final Tritium Experiments**  \n   The Joint European Torus (JET) conducted its final deuterium-tritium experiments in late 2025, achieving a peak fusion energy output of 69 megajoules over 5 seconds, extending its own 2022 record. Data from JET is now being used to refine ITER’s operational parameters.  \n   - **Source:** [UK Atomic Energy Authority – JET Final Results](https://www.ccfe.ac.uk/JET-final-campaign)\n\n4. **Helion Energy Begins Fuel Testing at Polaris Plant (Washington State)**  \n   Helion Energy started fuel injection tests at its P","keywords":["zo-research","climate-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"},"dateCreated":"2026-04-16T06:32:06.650823Z","dateModified":"2026-05-09T02:23:02.706784Z","additionalProperty":[{"@type":"PropertyValue","name":"trust_level","value":45},{"@type":"PropertyValue","name":"verification_status","value":"unverified"},{"@type":"PropertyValue","name":"provenance_status","value":"valid"},{"@type":"PropertyValue","name":"evidence_level","value":"ai_generated"},{"@type":"PropertyValue","name":"content_hash","value":"123054ccde8fccf1e48ff9af98a062e024caf9fba5b03aadea1151d0e0581ef0"}]}
