Intrinsic toroidal plasma rotation in the scrape-off-layer

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

The origin and nature of intrinsic toroidal plasma rotation in the scrape-off-layer are theoretically investigated. We discuss and analytically estimate three mechanisms that give rise to SOL toroidal rotation: turbulent momentum transport associated with ...

Study of plasma fluctuations in new closed flux-surface configurations of the TORPEX experiment

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Joaquim Loizu Cisquella, Fabio Avino, Sébastien Jolliet, Annamaria Mosetto

The TORoidal Plasma EXperiment (TORPEX) is a Simple Magnetized Torus (SMT) where open helical magnetic field lines are obtained from the superposition of a small vertical component on the main toroidal field. The SMT configuration features the main driving ...

EUV ionization of pure He nanodroplets: Mass-correlated photoelectron imaging, Penning ionization and electron energy-loss spectra

Marcel Drabbels, Nils Benedict Brauer

The ionization dynamics of pure He nanodroplets irradiated by EUV radiation is studied using Velocity-Map Imaging PhotoElectron-PhotoIon COincidence (VMI-PEPICO) spectroscopy. We present photoelectron energy spectra and angular distributions measured in co ...

Power distribution in the snowflake divertor in TCV

Basil Duval, Stefano Coda, Holger Reimerdes, Benoît Labit, Federico Nespoli, Wouter Vijvers

TCV experiments demonstrate the basic power exhaust properties of the snowflake (SF) plus and SF minus divertor configurations by measuring the heat fluxes at each of their four divertor legs. The measurements indicate an enhanced transport into the privat ...

Imaging of turbulent structures and tomographic reconstruction of TORPEX plasma emissivity

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Davoud Iraji

In the TORPEX [ A. Fasoli et al., Phys. Plasmas 13, 055902 (2006) ], a simple magnetized plasma device, low frequency electrostatic fluctuations associated with interchange waves, are routinely measured by means of extensive sets of Langmuir probes. To com ...

Three pulse UV photon echo studies of molecules in solution: Effect of the chirp

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Ahmad Ajdar Zadeh Oskouei

We report on the electronic dephasing times of the nonpolar chromophore diphenylacetylene (DPA) in ethanol and in cyclohexane (polar and nonpolar solvents respectively) by photon echo measurements in the ultraviolet. Contrary to previous reports, we observ ...

Comparing magnetic triggering of ELMs in TCV and ASDEX Upgrade

Yves Martin, Laurent Villard, Jonathan Bryan Lister, Sun Hee Kim

Frequency locking of edge localized modes (ELMs) to the vertical plasma movements induced by magnetic perturbations first demonstrated in TCV was successfully repeated in ASDEX Upgrade. However, the ELMs were triggered in ASDEX Upgrade when the plasma was ...

Protection and Fundamental Vulnerability of Global Navigation Satellite Systems (GNSS)

Panagiotis Papadimitratos, Aleksandar Jovanovic

An increasing number of mobile applications and services require that devices are aware of their location. Global navigation satellite systems (GNSS) are the predominant enabling technology. But location information provided by commercial GNSS is not secur ...
