Abstract
In this work we study the douplasmatron ion source and the extraction problems of intensed ion beams. we investigation the extraction characteristics of the source and its beam quality under different expermental conditions. the beam quality is measured by a sensitive electronic device which records the ion density distribution of the beam.
