Currents of two solenoid coils and steering magnets in LEBT are optimized with extraction and acceleration voltages for static acceleration in ion source (IS) which decides on an initial emittance diagram of H⁻ beam. As a result of LEBT and IS parameter optimization, beam transmission rate of RFQ has been reached up to 96 % in 50 mA H⁻ current operation. Moreover, PIC-MC (Particle-In-Cell Monte-Carlo) simulation model is developed for H⁻ transport in LEBT. Comparison between experimental and numerical results are presented to clarify beam physics from IS exit to RFQ entrance.
