That boosts the effectiveness of toroidal field for confinement but makes TF coil design and mechanical stress management brutal\u2014bending, hoop stress, and limited space for structure and services.<\/li>\n\n\n\n<li><strong>Copper TF coils (for ST40):<\/strong><br>ST40 uses copper magnets rather than HTS for the main device, but it sits on Tokamak Energy\u2019s roadmap toward HTS\u2011based high\u2011field STs.
