Gas puff imaging (GPI) is a diagnostic of plasma turbulence which uses a puff of neutral gas
at the plasma edge to increase the local visible light emission for improved space-time …

An overview of results of negative triangularity (NT) studies from the ASDEX Upgrade
tokamak (AUG) is given. Moderate values of the triangularity in the range of δ average≈ …

A multidiagnostic approach, utilizing Langmuir probes in the midplane, X-point and divertor
walls, along with lithium beam and infrared measurements is employed to evaluate the …

The I-mode is a plasma regime obtained when the usual LH power threshold is high, eg with
unfavourable ion $\nabla B $ direction. It is characterised by the development of a …

A summary of recent results on filamentary transport, mostly obtained with the ASDEX-
Upgrade tokamak (AUG), is presented and discussed in an attempt to produce a coherent …

In order to understand the mechanisms that determine the structure of the high confinement
mode (H-mode) pedestal, the evolution of the plasma edge electron density and …

In this work we carry out quantitative measurements of particle and heat transport associated
to SOL filaments in a tokamak, and relate density shoulder formation to the advection of …

The spatio-temporal interplay between turbulence, mean and zonal flows has been
investigated at the L–H and H–L transitions in the edge region of the ASDEX Upgrade …

Over previous campaigns, an intense experimental program on advanced tokamak (AT)
scenarios, has been carried out at the ASDEX Upgrade tokamak with full-tungsten wall …

Advanced tokamak (AT) scenarios applying additional heating during the current ramp
(early-heating) usually require many iterations if developed fully empirically. To reduce the …
