Simulation Study on Duoplasmatron With Optimization of Ion Beam Extraction System

The ion beam extraction system for various ion sources must be designed and evaluated using optimized parameters such as the gap distance between electrodes, applied voltage, and beam properties, using several different programs. SIMION, a 3-D simulation program, can transport various particles at once, and it is useful for simulating beam trajectories from the ion source and the beam line. PBGUNS can be used to calculate the effect of the gap between the plasma electrode and the extraction electrode on the ion beam properties. We propose combining the SIMION and PBGUNS results to compensate for problems in the calculation for the plasma. The calculation result from PBGUNS is utilized to perform ion beam extraction, which is close to the plasma model in SIMION, which can be used to easily simulate beam trajectories and model electrodes. We proposed a simulation method using SIMION to develop a model using plasma information from the PBGUNS result.
