Step inside Tokamak Energy’s Demo4 hall and see the biggest magnet demonstrator the team has built so far. This system isn’t just coils and cables. It’s a full 3D toroidal and poloidal coil setup designed to validate real fusion power-plant scale behaviour. From patented partial insulation in the toroidal field coils to fully insulated poloidal coils, Demo4 tests manufacturing repeatability, high magnetic fields, heavy compressive loads, and coil-to-coil interaction. Plus, you’ll see the cryogenic and power infrastructure that makes it all run, and the control room where every signal is tracked. #FusionEnergy #Tokamak #Superconductors #Engineering #CleanEnergy
