Plasma detachment in JET Mark I divertor experiments
The experimental characteristics of divertor detachment in the JET tokamak with the Mark I pumped divertor are presented for Ohmic, L-mode and ELMy H-mode experiments with the main emphasis on discharges with deuterium fuelling only. The range over which divertor detachment is observed for the various regimes as well as the influence of divertor configuration, direction of the toroidal field, divertor target material and active pumping on detachment will be described. A method to evaluate the degree and window of detachment is proposed and all the observations of the JET Mark I divertor experiments summarized in the light of this new quantitative definition of divertor detachment.
