　　In a high intensity volume-produced H⁻ ion source, H⁻ ion production processes are great affected by electron temperature and gas pressure distribution within the discharge chamber. The H-/e ratio within an extracted H⁻ ion beam is much depended on the electron absorption within the extraction system. At Peking University (PKU), lots of experiments were carried out for better understanding H⁻ processes and electron dump on our 2.45 GHz microwave driven Cs-free permanent magnet volume-produced H⁻ source. Detail will be given in this paper.
