abstract = {{China Institute of Atomic Energy (CIAE) has developed a series of multi-cusp H⁻ ion sources (IS) with DC beam intensity ranging from 3 to 18 mA for high intensity proton cyclotron uses such as cyclotron PET application, neutron source and boron neutron capture therapy (BNCT) facilities. Based on the previous experiences, a new project of radio frequency (RF) antenna driving ion source has been launched for pulse accelerator research. This new ion source is expected to provide over 100 mA peak intensity H⁻ beams of 60 keV and a longer maintenance interval than conventional filament-driving ion sources above. Impedance matching is indispensable for efficient RF power coupling in the whole working process of the ion source for high-intensity H⁻ beam extraction. In this paper, impedance characteristic of the IS antenna with various plasma loading is analyzed. Eight typical matching topologies are discussed on their electrical requirements. A type-L and a type-γ network are finally selected for the 2 MHz and 13.56 MHz chains respectively. This design may provide a better compromise between the matching performance and the cost of implementation for a wide dynamic loading range. Design of the network is evaluated on the power delivering efficiency in each of the two RF chains and isolation between one and the other. The IS structure and near-future work plan are also presented.}},
