A radio-frequency ion source has been developed in the Budker Institute of Nuclear Physics, Novosibirsk. Ion source is designed to operate in cw mode with beam modulation. The ion source works with hydrogen at 50kV producing an ion beam current of up to 70mA. The beam is extracted and accelerated by using a four electrode ion-optical system with single aperture. Initial beam diameter is 8 mm. The measured beam divergence is less than 0.5 deg. half angle.

This paper describes the experimental results obtained during the ion source testing. Ion source can be applied in many areas including plasma diagnostic, accelerator technique, ion implantation, etc.
