A New Technique for Diagnosing Multi-charged Ion Beams Produced by ECR Ion Source

摘要

In order to study the transmission properties of multi-charged ion beams between the ECR ion source and the analyzing magnet, a new diagnostic system composed of three Wien-filters with three single-wires has been built and installed on the IMP ECR source test bcnch. The single-wire is used to measure the beam profile and the beam density distribution, and the Wien-filter is used to measure the charge state distribution of ion beam.
