Overview of Beam Instrumentation at GSI

Beam instrumentation at GSI, specifically focusing on IPMs, plays a crucial role in managing various aspects of accelerator operations. The images and descriptions provided highlight the use of IPMs for setting up different ion sorts, beam width monitoring, cooling and injection optimization, and facilitating experiments. The SIS18 operation examples showcase the diverse demands handled by the facility, ranging from different ion sources to consumer-specific beam intensity and focusing requirements.
