Abstract

This report records some specific observations of MHD activity in ASDEX discharges. A limited set of discharges were examined; the discussion of the data attempts to relate the ASDEX observations to observations made on the Doublet III and PDX tokamaks and to theoretical work on high beta MHD modes at GA and PPPL. Three topics are discussed. The first topic is the detailed analysis of the time history of MHD activity in a beta limit discharge. The second topic is the very new observation of the fishbone-like mode in a discharge heated by combined neutral beam and ion cyclotron heating power. The third topic is the search for ELM precursors in discharges designed to have no other competing and complicating MHD activity.
