Abstract

Electron cyclotron heating (ECH) and electron cyclotron current drive (ECCD) have progressed from being the subject of experiments to being a prime tool for carrying out experiments on other topics. ECH has different characteristics than neutral beam heating: ECH heats only the electrons, heats very locally and controllably, does not inject momentum or particles, and may be arranged to drive highly localized currents or to just heat. These differences make ECH useful in a very wide range of experiments.
