The story of FUSION
A procedural journey through eight stages of magnetic-confinement fusion. The visuals and readings are illustrative.
Ignition
A first current starts the narrative. The word “ignition” here means the beginning of the experience.
The machine
A vacuum chamber, toroidal and poloidal field coils, central solenoid and divertor surround the plasma.
Confinement
Toroidal and poloidal magnetic fields form twisted paths that help confine charged plasma particles away from the walls.
Plasma
Heating ionizes the gas and energizes its particles. The experience illustrates a temperature approaching 150 million degrees Celsius.
Instability
Disturbances can disrupt magnetic confinement and increase energy loss.
Control
Measurements inform adjustments to magnetic fields and heating to manage the plasma boundary.
Star
Deuterium and tritium can fuse into helium-4 and a neutron, releasing 17.6 MeV per reaction. Charged helium can heat the plasma. Neutrons carry energy outward.
Future
Future fusion plants aim to turn captured heat into useful electricity. This artwork does not claim net power or plant performance.
