The physics of divertors in tokamaks is reviewed, primarily from an experimental point of
view, although where possible simple analytic modelling is included. The paper covers the …

This paper reviews progress in the understanding and application of electrical probes for the
diagnosis of tokamak edge plasmas. Langmuir probes are still one of the most commonly …

Abstract Effects of the plasma boundary can have a substantial influence on the behaviour of
the entire plasma in tokamaks. Progress in the field, particularly that over the last decade, is …

Plasma profiles and flows in the low-and high-field side scrape-off-layer (SOL) regions in
Alcator C-Mod are found to be remarkably sensitive to magnetic separatrix topologies (upper …

We present a novel concept to tackle the power exhaust challenge of a magnetically
confined fusion plasma. It relies on the prior establishment of an X-point radiator that …

Transport physics in the divertor and scrape-off layer of Alcator C-Mod is investigated for a
wide range of plasma conditions. Parallel (∥) transport topics include: low recycling, high …

A new “Mirror Langmuir Probe” diagnostic, combined with a double-coil scanning magnetic
probe, is used to interrogate Alcator C-Mod's quasi-coherent mode (QCM) with …

Gundestrup is a Langmuir/Mach probe array which measures the flow velocity in the scrape‐
off layer of Tokamak de Varennes (TdeV). It is based on the concept of a Mach probe where …

Deuterium gas injected into ELMing H mode divertor discharges in the DIII-D tokamak
typically reduced the total power at the divertor target~ 2 times and the peak heat flux~ 3 to 5 …

A new system of probes was recently installed in the divertor of tokamak COMPASS in order
to investigate the ELM energy density with high spatial and temporal resolution. The new …
