A simple method for ion deceleration system has been studied to adopt an axial-injection beam line at NIRS-930 cyclotron. An advantage of the method utilizing the decelerator is to allow high-current ion beam extracted from an ECR-ion source due to operate high potential difference between the source and extractor. The decelerator is operate by DC-voltage consists of appropriate electrode assembly. Electric field for the decelerator is carefully designed with the aid of 3D-field simulation code. Some properties of the decelerator as well as the design studies and simulation results are presented.
