Ultrafast X-Ray Summer School

The Ultrafast X-Ray Summer School (UXSS) is an annual meeting on X-ray science aimed at PhD students and post-docs, in its 19th iteration. The program consists of lectures given by distinguished scientists in core areas of X-ray Science, topical focus and technical talks, a tour of the  Swiss Free Electron Laser (SwissFEL), and guided hands-on project work in which the participants work out a mock proposal for beam time which will be evaluated at the end of the school.

The plenary lectures cover the foundational principles and current state-of-the-art in ultrafast X-ray applications across a broad spectrum of scientific domains:

• Fundamentals of X-ray free-electron lasers

• Theory of x-ray matter interaction

• Atomic and molecular physics

• Ultrafast chemical dynamics

• Condensed matter physics

• Structural biology

• Matter in extreme conditions.

The focus talks and technical notes will cover current topics related to ultrafast X-ray sciences:

• Attosecond science

• Coherent diffractive imaging

• X-ray optics

• Detector technologies

• Sample delivery systems

• Quantum simulations.

We hope you will join us for a productive and instructive event this summer.

The Organizers:

Camila Bacellar & Christoph Bostedt (PSI, local chairs)
Dominik Oberthür (CFEL/DESY, co-chair)
Benjamin Ofori-Okai (PULSE Institute/SLAC, co-chair)

The Ultrafast X-ray Summer School (UXSS) is jointly organized by CFEL, the PULSE institute at SLAC, and the Paul Scherrer Institut (PSI). The summer school has a long history dating back to the first UXSS in 2007. The UXSS 2025 is hosted by the Paul Scherrer Institut (PSI) in Villigen, Switzerland.
