Beamline Optics Design and Simulation Workshop

19 May 2025, 09:00 → 22 May 2025, 19:00 Europe/Berlin

Building 1b, Room 4ab (DESY)

Kai Bagschik (FS-PETRA-BO (Beamline Optics Simulation)), Nazanin Samadi (DESY)

This workshop offers a comprehensive, hands-on introduction to the design, modeling, and optimization of optical systems for synchrotron and X-ray beamlines. Participants will explore fundamental principles, advanced design strategies, analytical methods, and cutting-edge simulation techniques essential for modern beamline development.

Through a combination of lectures and practical sessions, attendees will gain experience using simulation tools inside OASYS, a powerful simulation environment, alongside analytical calculations to characterize and optimize beamline components. Key topics include:

• Synchrotron source properties – coherence, power, flux, and spectral characteristics
• Optical system design – mirrors, monochromators, lenses, and other key beamline elements
• Simulation techniques – ray tracing, wavefront propagation, and hybrid methods

Designed for scientists, engineers, and beamline professionals, this workshop provides the essential knowledge and skills needed to effectively simulate and optimize synchrotron optics. Whether you are new to beamline design or looking to enhance your expertise, this interactive training will offer valuable insights, practical techniques, and expert guidance to help you advance your work in X-ray optics, beamline and experiment design.

This workshop is organised by DESY Photon Science in the framework of the PETRA IV project.
