• In order to produce a well-focused high intensity ion beam, tests have been made on a plasma expansion ion source, in which the ion beam is extracted from the expanded plasma boundary formed in the plasma expansion electrode which is attached to the anode plate of the Duoplasmatron ion source. The effect of the plasma expansion electrode length on the ion beam focusing has been investigated. It is shown that the use of longer plasma expansion electrode results in obtaining well-focused high intensity ion beam. In such plasma expansion ion source, a 250 mA pulsed hydrogen ion beam with a half-angle divergence of 180 mrad has been obtained at an extraction voltage of 25 kV.
