Ion confinement properties of high performance plasmas studied by charge exchange neutral particle energy analyzers on TRIAM-1M

Description

High performance plasmas have been studied on TRIAM-1M. In 2.45 GHz lower hybrid current drive (LHCD) a transition to a high ion temperature (HIT) mode is observed. This mode shows both high ion temperature and good confinement. Onset conditions and heating properties are studied. In 8.2 GHz LHCD plasmas an enhanced current drive (ECD) mode, characterized by enhanced current drive efficiency and improved energy confinement, is obtained. In the ECD transition phase improvement of ion energy transport is preceded by the enhancement of the current drive efficiency. (author)
