Ion sources for use in research and applied high voltage accelerators

Brief description of design and performance of some ion sources, developed at the Efremov Institute for use in different types of accelerators, is given. They are several modifications of duoplasmatron ion source including H-version; RF-, Penning, Freeman and ECR ion sources for positive ion and cesium sputter source for negative ion production. Extracted current range spans 10/sup -4/-10/sup +2/ mA.
