The upgrade program of the AVF Cyclotron in RCNP is under way for the improvement of the beam quality and intensity. A new Low Energy Beam Transport(LEBT) system was designed to match the injected ion beam to the acceptable phase space in the center region of the AVF cyclotron for achievement of high injection transmission. This paper summarizes the design of the LEBT system, which transports beams from 18 GHz Superconducting ECR ion source, 2.45 GHz ECR proton source, 10 GHz NEOMAFIOS and NANOGUN ECR sources, polarized ion source and Duoplasmatron to the inflector electrode with high intensity and low emittance. This paper introduces optimum configuration of the LEBT magnets and the design of the strength of each magnet based on the calculation by using MAD-X.
