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.
