    Tokamak Energy HTS fusion magnets: Demo4 test insights for design engineers

    Tokamak Energy HTS fusion magnets: Demo4 test insights for design engineers

    First reported on New Civil Engineer

    30 Second Briefing

    Tokamak Energy has completed a 14‑month test campaign on Demo4, its high‑temperature superconducting (HTS) magnet testbed in Oxford, aimed at validating magnet performance for compact spherical tokamak fusion reactors. The Demo4 system is designed to operate HTS coils at cryogenic temperatures while subjecting them to high magnetic fields and mechanical loads representative of reactor conditions, a critical step for future fusion power plant infrastructure. Results will inform structural design, thermal management and lifecycle performance of full‑scale HTS magnet assemblies for grid‑scale fusion demonstrators.

    Technical Brief

    • Scope is limited to magnet and cryogenic performance; plasma physics and full plant integration were not addressed.

    Our Take

    Tokamak Energy’s Demo4 work sits within a relatively small subset of the 53 Materials stories that deal with advanced superconductors, signalling that UK-based fusion materials R&D is still niche compared with the AI-heavy items dominating the 1,906 keyword-matched pieces in our database.

    A 14‑month continuous test campaign on Demo4 in the United Kingdom suggests a level of magnet reliability and operational stability that civil and infrastructure clients of New Civil Engineer’s audience would normally associate with late-stage demonstration rather than early lab-scale trials.

    Paladin rare earth recycling expansion: supply-chain takeaways for engineers

    Rare earth recycler Paladin EnviroTech is investing over US$5 million to expand its Ohio recovery facility from 40 to 150 tonnes per year by Q3 next year, targeting end-of-life hard drives, EV motors, generators, MRI machines and wind turbines containing neodymium, praseodymium, terbium and dysprosium (up to ~16% Dy in MRI magnets). Working with Western Digital and Critical Materials Recycling, Paladin uses a non-acidic selective leaching process achieving 97–98% rare earth recovery and about 90% total value recovery, feeding mixed rare earth oxides back into Western magnet supply chains.

    Breedon’s new CEO from 2027: strategic implications for materials project teams

    Breedon has appointed current chief financial officer James Brotherton as its next CEO from 1 January 2027, succeeding Rob Wood after a 12-year tenure with the construction materials group. Brotherton has been CFO since 2021 and co-developed Breedon’s “expand and improve” strategy, which underpinned its expansion into the US market and transfer to the London Stock Exchange’s main market. Wood, who became CEO in 2021, will step down from the board at end-2026 but remain an employee to support the leadership transition until September 2027.

    Chryso–Ecocem low‑carbon cement system: mix design notes for concrete engineers

    Saint-Gobain’s Chryso and Ecocem have launched a combined low‑carbon system pairing Ecocem ACT cement, which cuts cement emissions by up to 70%, with Chryso’s new superplasticiser EnviroMix 3150 ACT, formulated for this binder chemistry. The admixture–cement combination enables concrete mix designs achieving over 50% carbon footprint reduction, meeting GWR5 and above, while maintaining high flowability, low viscosity at low water–cement ratios, and workability retention beyond 90 minutes without segregation. On the former John Lewis HQ refurbishment in London, around 1,300 m³ of C20/25 and C30/37 ACT concrete is being pumped using EnviroMix 3150 ACT to validate performance under site conditions.
