Banc de mesure pour la motorisation d'un avion solaire

La première partie de ce travail, est axée sur la simulation. La théorie, connue depuis déjà pas mal de temps, est pratiquement toujours issue de simplification et d’hypothèse, hypothèses qui ne sont pas forcement vérifiées dans un cas réel. La simulation ...

Sawtooth control in fusion plasmas

Olivier Sauter, Stefano Coda, Timothy Goodman, Jonathan Graves, Andrei Martynov

Clear observations of early triggering of neo-classical tearing modes by sawteeth with long quiescent periods have motivated recent efforts to control, and in particular destabilize, sawteeth. One successful approach explored in TCV utilizes electron cyclo ...

Comparison of m=2, n=1 neo-classical tearing mode limits in JET and DIII-D

Olivier Sauter

Joint experiments have been conducted on JET and DIII-D to study m = 2, n = I neo-classical tearing modes (NTMs). Very similar instability behaviour is observed on both machines and the scaling of the mode island width with beta and the observation of n = ...

Tritium transport experiments on the JET tokamak

Henri Weisen

An overview is given of the experimental method, the analysis technique and the results for trace tritium experiments conducted on the JET tokamak in 2003. Observations associated with events such as sawtooth collapses, neo-classical tearing modes and edge ...

Power modulation capabilities of the 140 GHz/1 MW gyrotron for the stellarator Wendelstein 7-X

Stefano Alberti, Minh Quang Tran, Damien Fasel

In current tokamaks and, in particular, in future larger devices such as ITER, the control of neo-classical tearing modes (NTM) is essential for achieving high performance in terms of the beta limit. A commonly used scheme for NTM stabilization consists in ...

The design of an ECRH system for JET-EP

Timothy Goodman, Stefano Alberti, Hartmut Zohm

An electron cyclotron resonance heating (ECRH) system has been designed for JET in the framework of the JET enhanced performance project (JET-EP) under the European fusion development agreement. Due to financial constraints it has been decided not to imple ...

From current-driven to neoclassically driven tearing modes

Olivier Sauter, Timothy Goodman, Holger Reimerdes, Antoine Pochelon

In the TCV tokamak, the m/n = 2/1 island is observed in low-density discharges with central electron-cyclotron current drive. The evolution of its width has two distinct growth phases, one of which can be linked to a "conventional" tearing mode driven unst ...

Electronic properties and resonant states in Al-Mn(-Si) alloys

Davor Pavuna

Experimental studies of quasi-crystalline Al100-xMnx(Si) alloys have shown that the magnitude of electrical resistivity as well as the excess specific heat term Δγ are proportional to the percentage of manganese in the samples as is the case in dilute Al-M ...
