The dust collection and analysis strategy in ASDEX Upgrade (AUG) is described. During five
consecutive operation campaigns (2007–2011), Si collectors were installed, which were …

The calculation of the trajectories and main physical parameters (eg mass, temperature,
electric potential) of an ensemble of several representative dust particles has recently …

The collection and emission of electrons from a spherical body in the Space-Charge Limited
(SCL) regime are investigated. When a Virtual Cathode (VC) in the potential profile around …

Dust grains in fusion devices may be radioactive, contain toxic substances, and may
penetrate into the core plasma resulting in the termination of plasma discharges. Therefore …

The effect of plasma turbulence on the trajectories of dust particles is investigated for the first
time. The dynamics of dust particles is computed using the ad hoc developed Dust Injection …

The occurrence of transient impurity events (TIE) leading to intense radiation spikes in JET
plasma discharges has been studied since the installation of the ITER-like wall (ILW). To …

We report a Bidirectional Electrode Control Arm Assembly (BECAA) for precisely
manipulating dust clouds levitated above the powered electrode in RF plasmas. The …

The effect of dust grains on the parametric coupling of neutral beam driven ion–cyclotron
wave instability with a lower hybrid pump wave is studied. A high amplitude lower hybrid …

The effect of magnetic field on the electron emission yield from a small spherical dust grain
immersed in a plasma is investigated. It is demonstrated that, due to their gyromotion, some …

Since the installation on the Joint European Torus of the ITER-like Wall (ILW), intense
radiation spikes have been observed, especially in the discharges following a disruption …
