5th Southern Scattering School on Polymers

Jul 15-17, 2024 

School of Polymer Science and Engineering, USM

​

   

Overview:

    This school will provide a practical guide for students in the Southeast US region to access the state of art X-ray tool at the USM.  This school will cover several important X-ray scattering techniques including small angle scattering, wide-angle scattering, grazing incident thin-film scattering. The school will address topics that are not commonly included in textbooks or class lectures, and typically obtained only through hand-on training. The topic will be covered including:

 

• a session of scattering/diffraction theory

• hands-on sessions at Xenocs SAXS/WAXS

• a session on scattering/diffraction data analysis

• the lecture will be recorded and provided for student's future reference ( new feature) 

​

Expected outcome: 

    Students will be able to understand the fundamentals of X-ray scattering, operate the instrument at various scattering geometry and perform simple data analysis. 

​

The workshop is free of charge for student and faculty.
