This paper reviews measurements of edge plasma turbulence in toroidal magnetic fusion
devices with an emphasis on recent results in tokamaks. The dominant feature of edge …

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 …

We consider “lattice glass models” in which each site can be occupied by at most one
particle, and any particle may have at most ℓ occupied nearest neighbors. Using the cavity …

In this paper we present a statistical study of edge fluctuations taken with the gas puffing
imaging (GPI) diagnostics. We carry out a comparison of GPI signal from an extensive …

The edge of fusion experiments is a region where strong gradients develop, together with
the presence of strong fluctuations due to turbulence. The thermal helium beam diagnostic …

The edge of the reversed field pinch experiment RFX-mod (R= 2 m, a= 0.46 m) is
characterized by a complex magnetic topology and strong pressure gradients. A set of fast …

Coherent structures emerging from turbulence background have been detected in the edge
region of the RFX-mod Reversed Field Pinch fusion device by using a new and original …

A common feature of magnetized plasmas is the presence of fluctuations, which can lead to
fully developed turbulence. Often large events—called bursts—emerge from the remaining …

The reversed field pinch device RFX-mod (⁠ R= 2 m⁠, a= 0.5 m⁠) has started plasma
experiments late in 2004. During the first year of operation a gas-puff imaging diagnostic has …

Plasma–wall interaction is one of the most important issues that present magnetic
confinement devices have to face. In the RFX-mod reversed field pinch experiment plasma …
