We present an overview of the development programme including details of the enabling technologies, the key modelling methods and results, and the remaining challenges on the path to compact fusion. 100 million degrees is the temperature required to force together charged deuterium and tritium particles that naturally repel each other and get them close enough together to fuse. Soon after, the whole tokamak was dismantled and moved to our new, larger facility. Tokamak Energy Ltd, UK, is developing spherical tokamaks using high temperature superconductor magnets as a possible route to fusion power using relatively small devices. The toroidal field (TF) magnets work with the poloidal field magnets to create a closed field pattern that confines the hot plasma and holds it away from the walls of the Inner Vacuum Chamber. The divertor coils – centre, top and bottom – stretch the plasma vertically and guide the plasma exhaust to a dedicated region where it can be effectively removed. To get the right conditions for fusion, you must create plasma – an electrically-charged gas. Terms of use. ST40 uses a novel technique to generate and heat the plasma – Merging Compression.
