    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.

    McHale’s new Metso Lokotrack crushers: design and efficiency notes for plant engineers

    Metso distributor McHale Plant Sales is taking orders in the UK and Ireland for two new Lokotrack units – the 70‑tonne LT400RS diesel‑electric mobile impact crusher and the LT200HPX mobile cone crusher with integrated screening – with deliveries from early 2025. The LT400RS, built around a 250 kW Nordberg NP1213MR impactor and 430 kW genset, targets concrete, asphalt and mixed demolition waste containing rebar and wood, using a 6.4 m² two‑deck screen, wind sifter and electromagnet to improve separation, fuel use and CO₂ output. The LT200HPX packages a Nordberg HP200e cone, two‑deck pre‑screen and 5.6 m² product screen on a single track chassis with wide conveyors and smart folding for high‑capacity, easily transported hard‑rock and aggregate production.

    Heidelberg low carbon concrete at 33–35 Piccadilly: mix design notes for engineers

    Heidelberg has supplied low carbon concrete, using carbon capture–decarbonised cement and GGBS, to Realtime Civil Engineering and Kier for the Crown Estate’s 33–35 Piccadilly redevelopment in central London. The mix design replaces a significant portion of Portland clinker with ground granulated blast-furnace slag, cutting embodied CO₂ compared with conventional CEM I concrete while maintaining structural performance suitable for a high-end commercial building. For contractors and designers, the project shows practical deployment of carbon capture–enabled binders on a constrained urban site with demanding specification control.

    Michelin tyres on Man UK trucks: durability and load gains for fleet engineers

    Michelin’s X Works Z2 and D2 315/80 R22.5 tyres are now available as original equipment on selected Man TGS construction trucks and tippers in the UK, offering the first B‑rated steer axle tyre for combined road and site use on fuel efficiency. Internal simulations show up to 10% longer life on steering axles and up to 25% on drive axles versus the previous generation, with a higher 158/150 load index adding 500kg capacity per single tyre position. The tyres are retreadable, feature reinforced sidewalls, 3PMSF winter approval and are compatible with electric trucks, targeting lower whole‑life operating costs.
