Abstract:
An ion source includes a base, a first chamber, a second chamber and an extractor. The first chamber is disposed downstream of the base and defines a first internal volume having a first pressure. The second chamber is disposed downstream of the first chamber and defines a second internal volume having a second pressure. The second pressure is less than the first pressure. The repeller electrode is disposed within the first chamber. The extractor is disposed downstream of the second chamber.
