Abstract

Advances pertaining to the study of quiescent H-mode plasmas in DIII-D ^a are discussed. It is stated that in many ways, quiescent H-mode (QH-mode) plasmas are the ideal H-mode plasma. Detailed ELITE calculations for the high triangularity plasmas have demonstrated that the plasma operating point is marginally stable to peeling-ballooning modes. It is observed that the EHO produces electron, main ions, and impurity particle transport at the plasma edge which is more rapid than that produced by ELMs under similar conditions.
