Cyclotrons are quite often to be used to accelerate different hydrogen ion beams with high intensity for different purposes around the World. At Peking University (PKU), special efforts were made on developing compact 2.45 GHz microwave driven ion sources with permanent magnets to generate high intensity H⁺, H²⁺, H³⁺ and H⁻ ion beams as well as other ion beams. For the positive ion beam, we can easily produce a 120 mA hydrogen ion beam with H⁺ fraction higher than 92% with a PKU standard 2.45 GHz ECR ion source. Its diameter is about 100 mm, its hight is about 100 mm. Also we have got 40 mA H²⁺ beam and 20 mA H³⁺ beam with a specific designed 2.45 GHz ECR ion source under different operation condition. The fractions of H²⁺ and H³⁺ are higher than 50% within the mixed hydrogen ion beams for each case. Recently, a Cs-free volume H⁻ source based on 2.45 GHz microwave was developed successfully in our lab. It can generate 45 mA H⁻ beam with duty factor of 10% and a 29 mA beam at DC mode at 35 keV. Its operation duty factor can vary from 1% to 100% and its power efficiency is about 20 mA/kW. Details of these sources will be presented in the paper.
