Design and numerical simulation of magnetic field for end-Hall ion source

Introduces the operating principle of end-Hall ion source for ion-beam-assisted deposition and discusses what magnetic field is required by end-Hall ion source. Then, describes the design principles and methods for the magnetism system of end-Hall ion source. Moreover, the magnetic field distribution of the ion source was simulated theoretically by ANSYS software, of which the results were compared with those of experiments. It was found that these two results conform well to each other. Analyzing the simulation results, a visual insight into magnetic field of the ion source is gained, thus providing a theoretical guidance for improving the design of end-Hall ion source.
