The world's largest fusion plant, the common European project JET at Culham in England, was the first where the 'sun fire' fetched to the Earth was burning.

Type of construction: TOKAMAK

Diamater of the vessel ring: 15 metres

Diameter of the chamber: 3 metres

Strength of the magnetic field: 4 Tesla.

For the exploration of many fundamental physical issues it is rather inconvenient to work already with the radioactive Tritium. In order to likely avoid negative surprises when building a reactor, ignition experiments have nevertheless been conducted at JET.
