BioCAT is offering its eleventh intensive HOW-TO course in BioSAXS. Students will have four days of virtual lectures and hands-on software tutorials on the basics of BioSAXS data collection and processing from expert practitioners in the field. Students will also be able to come on site or mail in samples for data collection on the BioCAT beamline (Sector 18 at the APS) after the lecture portion of the course.
The lectures will take place from 10/7/25 to 10/10/25 and are entirely virtual (via Zoom). Data collection will occur the week of 10/23/25. See the schedule below for details.

Registration
The course will provide a virtual set of lectures and tutorials via Zoom. Participants will be able to ask questions during both lectures and tutorials, and will have time to get help with analysis of their own data. They will also receive downloads of all course materials, including lecture slides and tutorials.
Note: This course is intended for researchers interested in scattering from monodisperse biological macromolecules in solution. It is NOT for soft matter, materials, or systems which are polydisperse.
Participants are also invited to come on-site or mail in samples for data collection and training. Data collection will occur during the week of 10/23/25.
There is no cost associated with the workshop (excepting travel and lodging costs for participants who come on site for data collection, which individual participants must cover) and registration will be granted upon review of a short application.
How to apply
To apply for a spot in the workshop fill out the short application. This requests basic contact and demographic data as well as your experience with SAXS and a paragraph about your research interests and proposed use of SAXS
Applications will be accepted through September 7th 2025, and reviewed the week of September 8th. You will be notified by email about your application.
