Overview of the SAXS2 beamline.

The SAXS2 beamline is an experimental station dedicated to Small Angle X-ray Scattering (SAXS) techniques in the hard x-rays energy range (6 to 12 keV) for studying the shape, size and structures of soft materials in the nanoscale with sizes ranging from 1 to 100 nm, with applications to molecular biology, medicine, life science, chemistry and material science.

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 the Py4Syn, developed at LNLS by SOL group.

All equipment has been synchronized through PXI to render the experiments easy and simple as possible. Long temperature scans with different furnaces are atomized and easy to performed.

HOW TO CITE THIS FACILITY

Users are required to acknowledge the use of LNLS facilities in any publications and to inform the Laboratory about any publications, thesis and other published materials. Users must also cooperate by supplying this information upon request. 

Support text for acknowledgements:

This research used resources of the Brazilian Synchrotron Light Laboratory (LNLS), an open national facility operated by the Brazilian Centre for Research in Energy and Materials (CNPEM) for the Brazilian Ministry for Science, Technology, Innovations and Communications (MCTIC). The _ _ _ beamline staff is acknowledged for the assistance during the experiments.

PUBLICATIONS
