In the framework of the study of the feasibility of an ECRH system for JET, the aim of this work is to verify that the foreseen 10 MW-170 GHz Electron Cyclotron (EC) input wave power would be sufficient for Neoclassical Tearing Modes control, crucial issue for operation at high ? and to determine how much the required power might be further reduced in the case of the microwave source modulation. The stabilization of low order (m,n) modes is discussed using a Generalized Rutherford equation and JET ELMy H-mode scenarios are considered in a wide range of operational magnetic field.

Abstract
In the framework of the study of the feasibility of an ECRH system for JET, the aim of this work is to verify that the foreseen 10 MW-170 GHz Electron Cyclotron (EC) input wave power would be sufficient for Neoclassical Tearing Modes control, crucial issue for operation at high ? and to determine how much the required power might be further reduced in the case of the microwave source modulation. The stabilization of low order (m,n) modes is discussed using a Generalized Rutherford equation and JET ELMy H-mode scenarios are considered in a wide range of operational magnetic field.File in questo prodotto:
