Description
Beam diagnostics play a central role in the commissioning, operation, and performance optimization of synchrotron light sources. Since the start of SESAME’s user operation, a variety of diagnostic systems have been employed to monitor beam properties, evaluate machine performance, and to support the development of advanced control and feedback systems. As operational requirements evolve toward higher beam stability, improved injection efficiency, and enhanced beam characterization, several diagnostic techniques and instrumentation upgrades have been developed and implemented.
This contribution presents an overview of selected diagnostic systems at the SESAME light source, the challenges encountered during their operation, and the developments undertaken to improve their performance. Topics including beam position monitoring and orbit stability studies which support the upgrade of the Slow Orbit Feedback system and the ongoing development of a Fast Orbit Feedback system will be discussed. The talk also discusses the development of an In-Air X-ray Detector for vertical beam size measurements using the hard X-ray from the Storage Ring dipole, providing a complementary tool for beam characterization. In addition, the diagnostic methods used to evaluate injection efficiency are presented, highlighting the use of current transformers and beam position monitors to better understand beam behavior during transfer from booster to storage ring and to optimize the injection process.
