轴对称电场中氘离子运动轨迹的仿真研究

Research on the trajectory of deuterium ions in the anxisymmetric electric field

建立了中子管加速系统模型,对加速电场分布和氘离子的运动轨迹进行了仿真.利用有限元分析软件探索了不同的加速间隙、电压、电极尺寸对离子轨迹的影响.得到了加速电极电场分布和离子束轨迹直观分布.该结果能够对中子管加速系统设计提供有价值的参考.

The model of neutron tube accelerator was established. The electric field distribution and particles trajectory were simulated in this model. The influence of different acceleration gap, voltage, electrode size on the ion trajectories is studied by ANSYS software. The result of the simulation shows valuable reference on the optimization and improvement of the neutron tube accelerator.
