Inertial Confinement Fusion

Definition

Inertial confinement fusion (ICF) is a type of nuclear fusion process where energy is generated by compressing and heating a fuel target, typically a small pellet containing a mixture of deuterium and tritium, to the point where nuclear fusion reactions occur. The confinement of the fuel is achieved through the inertia of the imploding material rather than by magnetic fields as in magnetic confinement fusion.
