A review of surface-plasma negative ions sources developed in the Budker Institute of Nuclear Physics for use in accelerators and neutral injectors for fusion experimental devices in last decade is presented. Physical processes, main properties and features of surface-plasma sources with various high-current discharge drivers are analyzed. Key issues and solutions in achieving the sources high power efficiencies, reliable long-term operation and easy maintenance will be discussed.
