A RF ion source for an electrostatic accelerator is designed and debugged. The influence of various factors on the RF ion source discharging is studied. Relationships between ion beam intensity and some parameters including plate voltage of the oscillator, gas pressure and extraction voltage are determined and analysed. An stable ion beam with 178 μA is obtained under the condition of the plate voltage of 580 V, the gas pressure of 8×10~(-4) Pa, the extraction voltage of 1.65 kV and the focusing voltage of 21 kV.
