In controlled nuclear fusion studies, neutral beam injection has become an effective method to heat plasma. The key part of a neutral beam injector is the ion beam system, whose performance determines the efficiency and effectiveness of neutral beam injection. The design and calculation methods of ion source and ion extraction and acceleration system of high power neutral beam injector are discussed in this paper. The calculation results of ion beam system of neutral beam injector HL-2 are given. In the strong current ion beam leads to accelerate the optical system bundle
