Increased interest in development of negative ions sources is related to the emergence of important applications of negative-ion beams. The list of those applications includes primarily tandem accelerators, including high-energy implantation and accelerator-based mass spectrometry, supercollimated beams, charge-exchange injection into cyclic accelerators and storage rings, charge-exchange extraction of beams from cyclotron, high-energy neutrals in plasma systems, charge-exchange of beams distribution, etc. Development of the sources of negative ions and their usage in academic research and industry are reviewed. Physical bases and designs of surface-plasma sources of negative ions alongside the history of their development are presented.
