Electron cyclotron resonant heating in the Tokamak TCV
The objective of the Tokamak à Configuration Variable (TCV) at the Centre de Recherches en Physique des Plasmas is to study the influence of elongation and strong shaping on tokamak performances. Since the plasma in TCV can be created with a large variety of shapes the auxiliary heating must be insensitive to the plasma configuration. Of all the heating methods Electron Cyclotron Resonant Heating (ECRH) has the best operational flexibility for heating of a wide range of different configurations, relying on steerable mirrors to deliver the power locally to the plasma. Moreover, mode control, current drive and current profile modifications by off-axis heating are other features which can be achieved with Electron Cyclotron Wave (ECW). This report presents the theoretical predictions for the absorption of and current drive (CD) efficiency due to ECW in TCV. The description and the status of the implementation of the ECW system are described.
