A three-dimensional (3D)simulation code IBSimu has been utilized for modeling of the transport and matching system of beam from the H-minus ion source into RFQ. A magnetic low energy beam transport (LEBT) line consisting of two solenoids and LEBT consisting of six magnetic quadrupole lenses were analyzed. The particle data from the 50 mA 100 keV ion beam extraction system simulations were taken as the starting data for the LEBT simulations. The main objective of the project was to achieve the required Twiss parameters and to minimize emittance growth at RFQ entrance. The LEBT consisting of two solenoids is more convenient in adjustment and as simulation results have shown this system offers more acceptable beam characteristics at the match point in comparison with LEBT composed of quadrupole lenses.
