High performance Joint European Torus (JET) plasmas for deuterium-tritium operation with the Mk II divertor
In deuterium plasmas, the highest neutron rates have been obtained in the hot-ion high-confinement mode (H-mode) which is ultimately limited by magnetohydrodynamic (MHD) phenomena when the pressure gradient approaches ideal ballooning and kink stability limits in the vicinity of the edge transport barrier. Results are reported confirming the MkII divertor's increased closure and pumping in this regime, progress in understanding the MHD-related termination is discussed, and the use of ion cyclotron resonance heating (ICRH) in combination with high power neutral beams to increase the neutron yield is described.
