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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
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 ...
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 ...

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 ...
