dc.description.abstract
Limit-cycle oscillations (LCOs) close to the power threshold of L- to H-mode transitions are
investigated in plasmas of ASDEX Upgrade. During this phase, referred to as I-phase, a strong
magnetic activity in the poloidal magnetic field B˙ with an up-down asymmetry is found. In
some cases, the regular LCOs during I-phase transition smoothly into a phase with intermittent
bursts which have similar properties to type-III edge localised modes (ELMs). Indications
of precursors during the intermittent phase as well as in the regular LCO phase point to a
common nature of the I-phase and type-III ELMs. The LCO frequency measured in a set of
discharges with different plasma currents and magnetic fields scales as f Bt I nT
