The main objective of the 1992–93 shutdown has been the installation of a pumped divertor inside of the JET vacuum vessel. Apart from the divertor components, comprising four poloidal field coils, a cryopump, and a new target structure. The belt limiters and continuous inner wall have been replaced by poloidal limiters, there is a completely new design of RF antenna, and a system of internal actively controlled saddle coils for disruption feedback stabilisation has been installed. External to the vessel there have also been some major updates to the hardware and plasma control systems, with a new fast radial field amplifier for vertical stabilisation, and a decoupling control scheme for the poloidal circuits. The as-built status of the plant and some results of the initial operation are described.
