Since the early 1980s, following the award-winning pioneering work done by Dr. Richard Geller, Dr. Claude Lyneis, and Dr. H. Postma; respectively from French Atomic Energy Commission, Lawrence Berkeley National Laboratory and the Oak Ridge National Laboratory, the use of electron cyclotron resonance for efficient plasma generation, especially to obtain large numbers of multiply charged ions, has acquired a unique importance in various technological fields. Many diverse activities depend on electron cyclotron resonance technology, including
