Electron cyclotron resonance heating

Technical Report:

Abstract

With the availability of high frequency (f{>=}50 GHz) high power microwave sources, Electron Cyclotron Resonance Heating (ECRH) is widely used in present-day tokamaks and stellarators and is planned for applications in ITER (International Thermonuclear Experimental Reactor). ECRH can be used over a broad spectrum of applications ranging from heating, with the aim of increasing plasma temperature and pressure, to plasma profile tailoring, in particular current profile tailoring, with the aim of enhancing or optimising stability and confinement properties. The presentation is structured as follows: the first points to be discussed when considering ECRH are accessibility and absorption, although it will be seen that it is not easy to separate one from the other due to the links between absorption and propagation. Some examples of the use of ECRH as a tool for different physics applications in tokamaks will be addressed. The applications envisioned for the Next Step (ITER) and for the Reactor will be the subject of the last chapter. (author) 16 figs., 3 tabs., 28 refs.
