  A RF driven plasma exciter for producing negative ions, aiming for heating and current drive neutral beam injectors for fusion applications, is in developing in Huazhong University of Science and Technology (HUST). In order to couple the maximum RF power to the source, the matching unit is designed to match the impedance of the source to that of the RF coaxial line. Firstly, a FEM model was built to estimate the equivalent circuit parameters of the source. Numerical predictions were compared with a small experimental setup to verify the accuracy of the fem model. Based on the numerical results, the RF coil and the matching components were carefully designed. Finally, the matching circuit for the source is developed and tested. Experimental results will be presented in the full paper.
