Loss of confinement due to reduction of the edge pedestal in JET

G.M. Fishpool1998年被引用 37Nuclear FusionIF 3出版社

There are various conditions in JET under which the energy confinement of aplasma is reduced from H mode towards L mode levels. Examples are reported here forwhich the loss of confinement is associated with a reduction of the electron pressurepedestal. This loss is brought about by strong gas puffing that increases the frequencyof edge localized modes (ELMs). The effect of ELMs on confinement is modelled, and usedto explain the observed degradation of confinement. The model is generalized forapplication to other machines.

JETには、プラズマのエネルギー閉じ込めがHモードからLモードのレベルへと低下する様々な条件が存在する。ここでは、閉じ込めの喪失が電子圧力ペデスタルの低下と関連している例を報告する。この喪失は、エッジ局在モード(ELM)の周波数を増加させる強いガス入射によって引き起こされる。閉じ込めに対するELMの影響はモデル化され、観測された閉じ込めの劣化を説明するために用いられる。このモデルは、他の装置への適用に向けて一般化される。
