用粒子束输运程序PBGUNS和iGun对两种不同离子源在单孔三极管引出柱上的束流引出进行了模拟。对于每个离子源，将模拟结果与在设备齐全的试验台上产生的实验数据进行比较。这两个代码都复制了被提取的离子束的定性行为，以增加和缩放在试验台上观察到的提取电极几何形状的变化。模拟得到的最佳束流和束流发射度的数值也与试验台数据吻合较好。
Ion beam extraction from two different ion sources with single aperture triode extraction columns was simulated with the particle beam transport codes PBGUNS and IGUN. For each ion source, the simulation results are compared to experimental data generated on well-equipped test stands. Both codes reproduced the qualitative behavior of the extracted ion beams to incremental and scaled changes to the extraction electrode geometry observed on the test stands. Numerical values of optimum beam currents and beam emittance generated by the simulations also agree well with test stand data.
