What is small-angle scattering?

Small-angle scattering is the premier technique for the size characterization of nanoscale objects.

Our Mission

The Small-Angle Scattering special interest group at Argonne National Laboratory has been created to promote awareness of the small-angle scattering facilities at the APS, IPNS, and elsewhere on the Argonne campus and to foster communications between the various research groups. Through this group, we believe we can build a strong user community for small-angle scattering at the APS, IPNS, and throughout Argonne.

Future courses organized by SAXS SIG:

SAXS Software Packages Irena and Nika

Next courses at the APS are scheduled for May 8 - 9, 2014, and May 15 - 16, 2014, as satellite meetings for APS users meeting.

These courses are already full. Future courses will be scheduled likely in end of August or during September 2014. If you would like to put your name on pre-registration list, contact Connie.

Hardware & software requirements

Successful small-angle x-ray scattering (SAXS) experiment requires appropriate data reduction and analysis tools. Igor Pro based packages Nika (for SAXS data reduction) and Irena (for SAXS data analysis) were developed during the last 10 years at the APS. They are already being used widely for material science SAXS at the APS and at other facilities worldwide. These tools are commonly taught during "Beyond Rg" - SAXS short course organized semi-annually by APS SAXS SIG (next one scheduled for March 2012). However, the main audience of the SAXS short course is new SAXS users, starting with their own SAXS program and therefore it focuses more heavily on experiments, theory etc. The time devoted in this course for software is insufficient for experienced experimenters interested in complex software applications.

Therefore, the APS SAXS Special Interest Group (SIG) is organizing this specialized, hands-on, course specifically on the SAXS software Nika and Irena. The course will be taught by the software author, Jan Ilavsky, APS staff member. In order to provide high educational value, the number of participants will be limited to 20. Participants are expected to have a high level of SAXS experience and bring their own computers (Windows or OSX). In addition, they are encouraged to bring their own SAXS experimental results.

The objective of the Small-Angle Scattering Short Course 2013/2014 will be to raise the capabilities of the small-angle scattering (SAS) community by providing an intermediate-level course for those in need of a better understanding of SAS theory, and techniques utilized at the APS.

The SAS short course will offer an overview of SAS theory, capabilities, and data reduction and analysis tools to enable the community to submit highly effective beam-time proposals and to facilitate better utilization of the resources at the APS.

This course will follow in the footsteps of the highly succesful similar courses in 2012, 2010, and 2008. If you would like to read the report from one of the previous courses, please see: 2012 Short course report
