摘要:

We present a new technique for selective, highly sensitive, absolute detection of different multiply charged ion species with equal charge‐to‐mass ratios in mixed multicharged ion beams. This is achieved by exploiting the statistics of potential electron emission as induced by the ion beams on a clean metal surface. The applicability of the method is illustrated by way of different practical examples.
