| Abstract: | Orloff-Swanson extraction lens has been widely used in field emission ion guns, however, no report of its application in ion guns with a plasma source has been published. Recently, the microwave ion gun was developed, which consists of a microwave plasma source and an Orloff-Swanson extraction lens. In this work, the ion beam optics of the microwave ion gun was studied experimentally and analyzed by numerically simulation. Our results showed that when apped to the ion gun with a plasma source, Orloff-Swanson extraction lens can also provide many good ion beam optics properties. |
