Abstract:
KIRAMS-30 cyclotron has been developed and implemented for radio isotope production. For the purpose of producing negative hydrogen ions and low energy beam injection to the central region of KIRAMS-30, 10 mA H(-) multicusp ion source with beam kinetic energies in the 20-30 keV range and the normalized 4 rms emittance less than 1 mm mrad was installed. The optimized ion source operating condition is presented and the correlation between the extracted beam current and ion source parameters is described for the performance enhancement of the ion source.
