中文摘要	Precise calculations of the beam optics are needed to design and optimize electrostatic accelerators. However, some beam transport programs can not simulate electromagnetic elements with complicated structures. This paper compares different transport programs including the Igun program developed to analyze electrostatic lens, which is often used to simulate ion sources. Based on Poisson/Superfish and Parmela's characteristics, the electric fields were calculated with the former program. Then the whole beam envelope and phase diagrams were simulated with Parmela for the special electrostatic elements. The whole beam line can be computed when the particle beam is within arbitrary pole boundary electromagnetic fields. In one beamline example, the beam size on the target was about 1 cm. The simulation results agree well with measured results.
