End of 1981 the Electron Cyclotron Heating (ECH) Division in the Institute for Plasma Research (IPF) of the University of Stuttgart was founded with members of the former Belt-Pinch, Theta-Pinch and “Plasmaus” (linear 2.45 GHz RF plasma device) Groups in order to develop a 28 GHz, 0.2 MW, 40 ms ECH system for plasma start-up, heating and confinement experiments on the Wendelstein W7-A Stellarator at IPP Garching. Since these experiments were very successful, later 70 GHz and 140 GHz ECH and non-inductive current drive CD systems were installed. This colloquium talk will review the first 10 years of ECH&CD experiments on Wendelstein Stellarators.
