    摘要: Charged particle beams with different charged particle currents are disclosed. In some embodiments, a method includes exposing a sample to a first ion beam having a first ion current at the sample, and exposing the sample to a second ion beam having a second ion current at the sample, where the first ion current is at least two times greater than the second ion current. In certain embodiments, a method includes creating a first ion beam at a first pressure, exposing a sample to the first ion beam, creating a second ion beam at a second pressure, and exposing the sample to the second ion beam, where the first pressure is at least two times greater than the second pressure.
