Although this is not an official ACA2025 workshop, we are proud to support this satellite event, which will take place independently and in advance of the main meeting.

This workshop series provides in-depth education on SAS theory, applications, and data analysis, including guidance on crafting effective beamtime proposals. Participants will benefit from demonstration experiments at APS beamlines, helping them identify the most suitable instruments for their research.

The program will cover the fundamentals of SAS, the theories and applications of SAXS and GISAXS, sample preparation, instrumentation, specialized applications across various fields, software training, and strategies for securing successful beamtime proposals.

More details will be available soon, but the workshop is typically a four-day event: two days of lectures, one day of hands-on experimentation, and one day dedicated to data analysis.

Please note that registration for this workshop is not available through the ACA2025 portal. Interested participants will need to register directly with the event organizers once registration opens.
