Gyrokinetic 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 ...

Trade Policy: Home Market Effect vs Terms of Trade Externality

Chiara Forlati

We study trade policy in a two-sector Krugman-type trade model with home market effects. We allow for three different instruments: tariffs, export taxes and production subsidies. For each instrument, we consider unilateral trade policy without retaliation. ...

Optimal Exchange-Rate Targeting with Large Labor Unions

Luisa Lambertini, Vincenzo Cuciniello

We study whether monetary policy should target the exchange rate in a two-country model with non-atomistic wage setters, non-traded goods and different degrees of exchange- rate pass through. Commitment to an exchange rate target reduces the labor market d ...

A model for the design of effective and resilient supply chain security management systems

Ximena Gutiérrez Rueda

The current business environment has become more risky and variable. In particular, the recent terrorist attacks against western economies have revealed the vulnerability of global supply chains. These events showed that companies that move cargo internati ...

Critical temperature gradient length signatures in heat wave propagation across internal transport barriers in the Joint European Torus

Alessandro Marinoni

New results on electron heat wave propagation using ion cyclotron resonance heating power modulation in the Joint European Torus (JET) [P. H. Rebut , Nucl. Fusion 25, 1011 (1985)] plasmas characterized by internal transport barriers (ITBs) are presented. T ...

The role of the radial electric field for the transition to high confinement regimes

Duccio Testa

The radial electric field E-r(x, t), and particularly its gradient, has been invoked by various theories and empirical models as a crucial parameter 'per se' for determining the transition to high confinement regimes, such as the onset of an internal trans ...

10-channel far-infrared polarimeter for the tokamak configuration variable

Patrick Blanchard, Henri Weisen, Roland Behn

A new far-infrared polarimeter diagnostic for the tokamak a configuration variable (TCV) is under construction at CRPP. It uses two FIR lasers at 432.5 mu m, optically pumped by a 120 W continuous wave CO2 laser. The two FIR cavities will be detuned such t ...

Design of a tangential phase contrast imaging diagnostic for the TCV tokamak

Stefano Coda, René Chavan, Alessandro Marinoni

A core density fluctuation imaging diagnostic is being developed for the TCV tokamak, employing a 7 cm wide CO2 laser beam transmitted through the plasma in a near-toroidal direction. The proposed system employs the phase contrast method and can resolve wa ...

Temperature oscillating regimes in Tore Supra diagnosed by MHD activity

This paper describes what we can learn on the regimes of spontaneous electron temperature oscillations discovered in Tore Supra from the analysis of MHD activity. Since the first observations of this oscillating behaviour of plasma equilibrium, and its int ...
