Blob motion and control in simple magnetized plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Davoud Iraji

The radial propagation of plasma blobs and possibilities of influencing it are investigated in the TORPEX toroidal experiment [Fasoli et al., Phys. Plasmas 13, 055902 (2006)]. The effect of changing the connection length and the neutral background pressure ...

Three-Dimensional Imaging of a Radially Propagating Plasma Blob Using Conditional Sampling Techniques

Ambrogio Fasoli, Ivo Furno, Benoît Labit, Christian Gabriel Theiler

We present 3-D imaging of plasma blobs, generated from ideal interchange turbulence in the TORPEX device, obtained by applying different conditional sampling techniques to electrostatic probe data. Time-evolving spatial profiles of electron density, temper ...

Relativistic Doppler effect in an extending transmission line: Application to lightning

Marcos Rubinstein, Abdolhamid Shoory

We present in this paper a thorough analysis of current wave propagation with arbitrary speed along an extending transmission line. We derive rigorous analytical equations in the time and frequency domains expressing the reflections of the current wave occ ...

A MULTIWAVELENGTH STUDY OF A SAMPLE OF 70 mu m SELECTED GALAXIES IN THE COSMOS FIELD. I. SPECTRAL ENERGY DISTRIBUTIONS AND LUMINOSITIES

We present a large robust sample of 1503 reliable and unconfused 70 mu m selected sources from the multiwavelength data set of the Cosmic Evolution Survey. Using the Spitzer IRAC and MIPS photometry, we estimate the total infrared (IR) luminosity, L-IR (8- ...

Structure and Bonding of Isoleptic Coinage Metal (Cu, Ag, Au) Dimethylaminonitrenes in the Gas Phase

Thomas Rizzo, Natalia Nagornova, Peter Chen

Dimethylaminonitrene complexes of IMesM+ (IMes = 1,3-bis(2,4,6-trimethylphenyl)- imidazol-2-ylidene; M = Cu, Ag, Au) were prepared in the gas phase and structurally characterized by high-resolution infrared spectroscopy of the cold species, ion-molecule re ...

Long-Term Monitoring Of Bright Blazars With A Dedicated Cherenkov Telescope

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

Flaring activity of Active Galactic Nuclei (AGN) in VHE gamma-ray astronomy is observed on timescales from minutes to years and can be explained either by the interaction of relativistic jets with the surrounding material or by imprints of the central engi ...

IceCube sensitivity for neutrino flux from Fermi blazars in quiescent states

Mathieu Ribordy

We investigate the IceCube detection potential of very high energy neutrinos from blazars, for different classes of hadronic models, taking into account the limits imposed on the neutrino flux by the recent Fermi telescope observations. Assuming the observ ...

Fluid code simulations of radial electric field in the scrape-off layer of JET

Richard Pitts

Recent simulations of JET and ASDEX Upgrade plasmas with EDGE2D and SOLPS, respectively, showed that upstream radial electric field in the scrape-off layer (SOL) is substantially below values expected from simple estimates, based on the effects of the pote ...

First measurements of oblique ECE with a real-time moveable line-of-sight on TCV

Olivier Sauter, Timothy Goodman, Christian Schlatter, Igor Klimanov

Electron cyclotron (EC) emission (ECE) radiometers viewing perpendicular to the magnetic field are common on nearly all tokamaks for measuring the electron temperature with good spatio-temporal resolution. Two such radiometers are installed on TCV, one loo ...

Astrophysical applications of gravitationally lensed quasars

Alexander Patrick Eigenbrod

Gravitational lensing describes how light is deflected as it passes in the vicinity of a mass distribution. The amplitude of the deflection is proportional to the mass of the deflector, called "gravitational lens", and is generally weak, even for large mas ...
