Abstract The JET 2019–2020 scientific and technological programme exploited the results of years concerted engineering work, including ITER-like wall (ILW: Be W divertor) installed in 2010, improved diagnostic capabilities now fully available, a major neutral beam injection upgrade providing record power 2019–2020, tested technical procedural preparation for safe operation with tritium. Research along three complementary axes yielded wealth new results. Firstly, plasma delivered scenarios...
Abstract In 2021 JET exploited its unique capabilities to operate with T and D–T fuel an ITER-like Be/W wall (JET-ILW). This second major campaign (DTE2), after DTE1 in 1997, represented the culmination of a series enhancements—new fusion diagnostics, new injection capabilities, refurbishment plant, increased auxiliary heating, in-vessel calibration 14 MeV neutron yield monitors—as well as significant advances plasma theory modelling community. DTE2 was complemented by sequence isotope...
Abstract The Active Gas Handling System (AGHS) stores, supplies and re-processes tritium for the JET fusion experiment. plant had not operated in this capacity recent years required upgrade recommissioning to enable use during latest campaigns. Thousands of transfers operations have now been performed with over 1 kg total supplied subsequently recovered reprocessed. This paper summarises AGHS providing examples from campaigns, presents knowledge gained lessons learnt. A summary sub-system...
Abstract Following the first deuterium–tritium experiment (DTE1) at UKAEA, modifications were investigated to Joint European Torus’ (JET) gas introduction (GI) systems increase feed capabilities of JET facility better support future campaigns. The GI comprise and distribution system in Active Gas Handling System (AGHS), neutral beam injection tritium modules on torus. During DTE1 about 100 g was supplied from AGHS users. second (DTE2) tritium–tritium (TT) just over 373 630 respectively users...
