Vdovin}, title = {Objectives, physics requirements and conceptual design of an ECRH system for JET}, abstract = {A study has been conducted to evaluate the feasibility of installing an electron cyclotron resonance heating (ECRH) and current drive system on the JET tokamak. The main functions of this system would be electron heating, sawtooth control, neoclassical tearing mode control to access high beta regimes and current profile control to access and maintain advanced plasma scenarios. This paper presents an overview of the studies performed in this framework by an EU-Russia project team. The motivations for this major upgrade of the JET heating systems and the required functions are discussed. The main results of the study are summarized. The usefulness of a 10 MW level EC system for JET is definitely confirmed by the physics studies. Neither feasibility issues nor strong limitations for any of the functions envisaged have been found. This has led to a preliminary conceptual design of the system. }, year = {2011}, journal = {Nuclear Fusion}, volume = {51}, number = {6}, pages = {063033}, month = {Jun}, isbn = {0029-5515}, doi = {10.1088/0029-5515/51/6/063033}, note = {ISI Document Delivery No.: 766MWTimes Cited: 2Cited Reference Count: 37}, language = {English}, }
