Tokamak operations in JET resumed in November 1985 after a major shutdown devoted to add new systems such as the first Neutral Beam Injection box, new carbon protection in the vessel, a third ICRF antenna and a single Deuterium pellet launcher. During all of 1986, experiments have been pursued and the results reported in particular at the EPS (Schliersee) and IAEA (Kyoto) meetings.
