D-T fusion scheme.

Thermonuclear fusion reaction between two isotopes of hydrogen, deuterium and tritium. The ignition temperature of this reaction is 160,000,000 kelvin. The fusion of the deuterium and tritium nuclei produces a helium atom nucleus, a neutron, and releases an energy of 17.53 MeV. The possibilities of igniting this reaction are being intensively studied because it has a relatively low ignition temperature, a large cross section and a sufficient yield to be used as an energy source in a thermonuclear fusion power plant.
