| Abstract: | CST EM studio and particle studio are used to simulate the cusp magnetic field, magnetic filter field, deflection magnetic field, and beam optics. The optimum magnetic configuration parameters have been determined by scanning surface magnetic fields of cusp magnets, filter magnets and deflection magnets: 4kG on 6 laps of cusp magnets around the ion source, 5.5kG on permanent filter magnets, and 2.5kG on deflection magnets. The performance of beam optics meets the requirements for neutral beam injection with 5~20kV extraction voltages and 50~160kV acceleration voltages. |
