Three-dimensional boundary turbulence simulations of a RFX-mod plasma in the presence of voltage biasing
M. Giacomin, N. Vianello, R. Cavazzana +3
Three-dimensional turbulence simulations of a RFX-mod diverted plasma are performed in the presence of a biasing electrode. The simulations show a strong suppression of turbulent t…
Lessons learned after three years of SPIDER operation and the first MITICA integrated tests
D. Marcuzzi, V. Toigo, M. Boldrin +139
ITER envisages the use of two heating neutral beam injectors plus an optional one as part of the auxiliary heating and current drive system. The 16.5 MW expected neutral beam power…
Numerical and experimental investigations of a microwave interferometer for the negative ion source SPIDER
R. Agnello, R. Cavazzana, I. Furno +4
The electron density close to the extraction grids and the co-extracted electrons represent a crucial issue when operating negative ion sources for fusion reactors. An excessive el…
Measure of negative ion density in a large negative ion source using Langmuir probes

Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…

Andrea Rigoni Garola, Gabriele Manduchi, Marco Gottado +4
The RFX-mod2 Nuclear Fusion experiment is an upgrade of RFX-mod, shutdown in 2016. Among the other improvements in the machine structure and diagnostics, a larger number of electro…
Evaluation of noise limits of a precision ADC for direct digital signal integration of magnetic measurements
Roberto Cavazzana, Marco Gottardo, Andrea Rigoni Garola
The characterization of laboratory plasma instabilities, magnetic reconnection and turbulence associated phenomena, require the simultaneous signal sampling from arrays of magnetic…
An active feedback recovery technique from disruption events induced by m=2 n=1 tearing modes in ohmically heated tokamak plasmas

We present experimental results of magnetic feedback control on the m=2, n=1 tearing mode in RFX-mod operated as a circular ohmically heated tokamak. The feedback suppression of th…
Spatiotemporal synchronization of drift waves in a magnetron sputtering plasma
E. Martines, M. Zuin, R. Cavazzana +5
A feedforward scheme is applied for drift waves control in a magnetized magnetron sputtering plasma. A system of driven electrodes collecting electron current in a limited region o…
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…
