1. A compact nuclear fusion reactor comprising a toroidal plasma chamber in which is confined a plasma comprising tritium and deuterium ions, and a plasma confinement system arranged to generate a magnetic field for confining the plasma in the plasma chamber, wherein:
the plasma confinement system is configured so that the major radius of the confined plasma is 1.5 m or less, preferably 1.2 m or less, preferably 1.0 m or less preferably 0.8 m or less, more preferably 0.6 m or less; the magnetic field in use includes a toroidal component of 5 T or less, preferably 4 T or less, preferably 3 T or less, more preferably 2 T or less; the plasma current is 5 MA or less, preferably 4 MA or less, preferably 3 MA or less, more preferably 2 MA or less, more preferably 1 MA or less; the aspect ratio is 2.5 or less, preferably less than 2.2, more preferably less than 2.0, more preferably less than 1.8, more preferably less than 1.7; and a fraction of a-particles generated in the reactor which are confined within the plasma is 0.4 or greater, preferably 0.5 or greater, more preferably 0.6 or greater, more preferably 0.7 or greater, more preferably 0.8, more preferably 0.9 or greater. |
