For the purpose of this presentation, the term Linac is narrowed down to comprise rf machines that accelerate ion beams at duty factors between about 5% and continuous operation. This group of Linacs includes proton and H- machines as well as accelerators utilizing multi-charged heavy ions, mostly for nuclear physics applications. Main types of ion sources serving these Linacs include Electron Cyclotron Resonance (ECR) sources, filament and rf driven multi-cusp sources, Penning (PIG) sources and duoplasmatrons. This presentation does not strive to attain encyclopedic character but rather to highlight current trends in performance parameters, major lines of development and type-specific limitations and problems, with emphasis on ECR and multi-cusp sources. The main technical aspects being discussed are ion production and beam formation.
