Electron Cyclotron Emission (ECE) And Correlation ECE Diagnostic On TCV
Laurie Porte, Philippe Marmillod, Matteo Fontana
The electron cyclotron emission (ECE) and correlation ECE diagnostics in TCV have been upgraded during its 2014 shutdown; this paper will provide a brief overview on their updated architecture and capabilities. The ECE system is equipped with two radiomete ...
2015Electron-Phonon Interactions and the Intrinsic Electrical Resistivity of Graphene
Nicola Marzari, Boris Kozinsky, Thibault Daniel Pierre Sohier
We present a first-principles study of the temperature- and density-dependent intrinsic electrical resistivity of graphene. We use density-functional theory and density-functional perturbation theory together with very accurate Wannier interpolations to co ...
Amer Chemical Soc2014An assessment of ion temperature measurements in the boundary of the Alcator C-Mod tokamak and implications for ion fluid heat flux limiters
The ion temperature is not frequently measured in the boundary of magnetic fusion devices. Comparisons among different ion temperature techniques and simulations are even rarer. Here we present a comparison of ion temperature measurements in the boundary o ...
2013Identifying the role of non-adiabatic passing electrons in ITG/TEM microturbulence by comparing fully kinetic and hybrid electron simulations
Stephan Brunner, Julien Stanislas Pierre Dominski
The response of passing electrons in Ion Temperature Gradient (ITG) and Trapped Electron Mode (TEM) microinstability regimes is investigated in tokamak geometry making use of the flux-tube version of the gyrokinetic code GENE [Jenko et al. 2000 Phys. Plasm ...

Christoph Hollenstein, Peter Ott, Pénélope Leyland, Philip Peschke, Sami Goekce
Dielectric Barrier Discharge in air at atmospheric pressure ...
2011Ab initio thermodynamics calculation of all-optical time-resolved calorimetry of nanosize systems: Evidence of nanosecond decoupling of electron and phonon temperatures
The thermal dynamics induced by ultrashort laser pulses in nanoscale systems, i.e., all-optical time-resolved nanocalorimetry is theoretically investigated from 300 to 1.5 K. We report ab initio calculations describing the temperature dependence of the ele ...
2010Gyrokinetic Simulations of Microturbulence in TCV Electron Internal Transport Barriers
Olivier Sauter, Laurent Villard, Stephan Brunner, Xavier Lapillonne
Using the Eulerian code GENE [1], gyrokinetic simulations of microturbulence were carried out under conditions relevant to electron-Internal Transport Barriers (eITB) in the TCV tokmak [2], generated under conditions of low or negative shear. For typical d ...
2010Ultrafast (but Many-Body) Relaxation in a Low-Density Electron Glass
We present a study of the relaxation dynamics of the photoexcited conductivity of the impurity states in the low-density electronic glass, phosphorous-doped silicon Si: P. Using subband gap optical pump-terahertz probe spectroscopy we find strongly tempera ...
American Physical Society2010Turbulent ion heating in TCV tokamak plasmas
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 ...
EPFL2009Modulation of electron transport during Swing ECCD discharges in TCV
Olivier Sauter, Timothy Goodman, Stefano Alberti, Costanza Zucca
Generation of a swing electron cyclotron current drive (swing ECCD), i.e. driving alternated, symmetric, positive or negative local ECCD, during a single discharge and at constant total input EC power, was performed at the Tokamak a Configuration Variable ...
