Basic Investigation of Turbulent Structures and Blobs of Relevance for Magnetic Fusion Plasmas

Similarly to neutral fluids, plasmas often exhibit turbulent behavior. Turbulence in plasmas is usually more complex than in neutral fluids due to long range interactions via electric and magnetic fields, and kinetic effects. It gives rise to many interest ...

Existence of subsonic plasma sheaths

Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella

The location of the plasma sheath edge, where quasineutrality is broken, is rigorously derived by using a kinetic description of the plasma. It is shown that sheaths can exist with arbitrarily small ion velocity at the sheath edge, thus violating the Bohm ...

On the 3D Reconstruction of Coronal Mass Ejections using Coronagraph Data

Coronal Mass ejections (CMEs) are enormous eruptions of magnetized plasma expelled from the Sun into the interplanetary space, over the course of hours to days. They can create major disturbances in the interplanetary medium and trigger severe magnetic sto ...

Sheath boundary conditions for plasma fluid models

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella

A new definition of the sheath edge is rigorously derived taking into account the kinetic properties of the plasma, and a consistent set of local sheath edge conditions is presented for the case of a magnetic field perpendicular to the wall. These local bo ...

Turbulent ion heating in TCV tokamak plasmas

Christian Schlatter

The Tokamak à configuration variable (TCV) features the highest electron cyclotron wave power density available to resonantly heat (ECRH) the electrons and to drive noninductive currents in a fusion grade plasma (ECCD). In more than 15 years of exploitatio ...

Study of the solar anisotropy of cosmic ray primaries of about 200 GeV energy with the L3+C muon detector

Qian Wang, Aurelio Bay, Horst Vogel, Eduardo Sanchez, Zhirui Xu, Werner Lustermann, Liang Sun, Jian Zhao, Yu Lei, Ji Hyun Kim, Zheng Wang, Matthias Weber, Xiao Wang, Yifei Guo, Xuan Yang

Context. Primary cosmic rays experience multiple deflections in the non-uniform galactic and heliospheric magnetic fields which may generate anisotropies. Aims. A study of anisotropies in the energy range between 100 and 500 GeV is performed. This energy r ...

On the Relationship Between the Signature of Close Electric Field and the Equivalent Corona Current in Lightning Return Stroke Models

Carlo Alberto Nucci

Engineering return stroke models can be categorized either as current generation (traveling current source type) models or current propagation (transmission line type) models. The current generation models are described among other parameters by a corona c ...

Particle-in-cell simulations of the impact of retarding field analyser probe head geometry on ion saturation current measurements

Richard Pitts

The Retarding Field Analyser (REA) is essentially the only practical tool for the measurement of ion energies parallel to the total magnetic field in the tokamak scrape-off layer plasma. One such device has recently been successfully employed at JET [1]. I ...

Multicriteria Optimisation of Small Hybrid Solar Power System.

Daniel Favrat, El Hadj Malick Kane

A new concept of small hybrid solar power system (HSPS) has been successfully demonstrated in the context of a project called SPS (Solar Power System). This plant integrates two rows of solar collectors, two superposed Organic Rankine Cycles (ORC) each equ ...

SPS : Projet d’une minicentrale pilote électro-thermo-solaire de 10 kWe - Partie A : Centrale solaire hybride

Daniel Favrat, El Hadj Malick Kane

Thermal solar power plants using Rankine cycles closely approach the present economical electricity prices, at least in the large power range. One of the advantages currently explored is the integration with other fuel based technologies in order to ascert ...
