Highly charged ion beam diagnostics at the mVINIS Ion Source

In order to determine position, dimensions and intensities of multiply charged ion beams at the mVINIS Ion Source, a novel method was developed based on a fluorescent screen and a commercial digital TV camera. The spatial characteristics of multiply charged ion beams (for example the ionization states of Ar2+ to Ar10+) have been precisely measured and analyzed at the TESLA Accelerator Installation for the first time. In this work, we discuss in details the characteristics of Ar8+ion beams. The obtained ion beam characteristics were compared with the results of previously applied conventional methods of ion beam diagnostics.
