On the genesis and nature of Palm Tree Modes in the JET tokamak
Christian Maszl, Volker Naulin, Roman Schrittwieser
Long-lived, highly localized structures called palm tree modes (PTM) are observed in the edge plasma of the JET tokamak. Although PTMs are well documented, little is known about th…
Direct observation of current in type I ELM filaments on Asdex Upgrade
N. Vianello, V. Naulin, R. Schrittwieser +8
Magnetically confined plasmas are often subject to relaxation oscillations accompanied by large transport events. This is particularly the case for the high confinement regime of t…
Observation of the ion-ion instability and its suppression mechanism in a dusty double plasma device
Arun Sarma, Bornali Sarma, Codrina Ionita +2
Ion-ion instability is excited due to the counter streaming of ion beams in any plasma system. An experiment has been carried out to observe the ion-ion instability in dusty plasma…
Electron dynamics at the initial stage of floating-sheath formation
Catalin Lupu, Davy D. Tskhakaya, Siegbert Kuhn +3
The problem of sheath formation in front of a conductive planar plate inserted into the plasma is formulated. Initially, the plate is assumed to be neutral. It is shown that the ch…
First result on a laser-heated emissive probe
Ramin Madani, Codrina Ionita, Roman Schrittwieser +1
The floating potential of a probe, emitting a sufficiently high electron current, yields a fairly accurate approximation of the plasma potential. This is an advantage in comparison…
Similarities between the generation and dynamics of concentric and non- concentric multiple double layers
George Amarandei, Cezar Gaman, Dan G. Dimitriu +3
We report new experimental results on the generation and dynamics of multiple double layers in front of a positively biased electrode immersed in a DP-machine plasma. Depending on…
