ABOUT THIS BEAMLINE


The SAXS1 beamline is an experimental station dedicated to Small Angle X-ray Scattering (SAXS), operating at a fixed energy of 8 keV. It focuses on structural investigations of materials and biological samples, from the nanometer to a hundred nanometer scale, with applications in material science, chemistry, gels, rheology, structural biology, environmental and geosciences. Other experimental technique available includes Wide Angle X-ray Scattering (WAXS).

Due to the high photon flux, time-resolved SAXS can be performed reaching sub-second time-resolution for kinetic studies.

Several sample environment are made available to the user community, such as (1) furnaces (Linkam THMS600*) allowing temperatures from -200°C up to 600°C, (2) stretching devices (Linkam TST350), (3) circulating solution system with a peristaltic pump for in situ studies, (4) stopped-flow device (Biologic*), (5) autosampler (Spark Holland) for automatic loading of protein solutions.

CONTROL AND DATA ACQUISITION

 

All beamline controls are done through EPICS (Experimental Physics and Industrial Control System), running on a PXI from National Instruments. The data acquisition is done using a Red Hat workstation with Python scripts, developed at LNLS with SOL group. CSS (Control System Studio) is used as a graphical interface to display and control the beamline devices.

 

APPLYING FOR BEAMTIME

 

Submission calls are usually announced twice per year, one for each semester. All the academic research proposals must be submitted electronically through the SAU Online portal. Learn more about how to submit a proposal here.

 

It is recommended that new users contact the beamline group members for discussing the experimental proposal before submission .
