FIFTH EUROPEAN TOKAMAK PROGRAMME WORKSHOP, TOLEDO 17 19 DECEMBER 1986. OVERVIEW ON 1986 JET RESULTS BY THE JET TEAM
The main parameters of JET are summarised, showing that the most significant improvements are - the extension of 5 MA discharges to a flat top duration of 4.5 s - the obtention of stable discharges at qpsi approximately equal 2.1 with B-T=1.7T and I-p=3.5 MA in preparation of future operations at 7 MA a total input power to the plasma reaching 18 MW - a plasma energy content close to 6 MJ in both cases of limiter and separatrix limited plasmas - an increase of the temperature of the plasma: up to 12.5 keV for the peak deuterium temperature in low density rd discharges with NBI and up to 8 keV for the peak electron temperature in He discharges with ICRF. - a record value of the fusion parameter n-i(o) T-i(o)tau-E of 2.102om-3 keV/s obtained during separatrix limited plasmas with enhanced confinement (H mode). Section 1 of this summary presents the machine conditions, Section 2 addresses dedicated experiments performed on JET like pellet injection, ultra long sawteeth studies and magnetic separatrix operations. Section 3 is about global plasma behaviour such as impurities, density limit, plasma temperature, energy confinement time and thermonuclear reactivity. Section 4 describes briefly the future changes to be made to JET and the resulting prospects.
