Description
SAXSLab Sapienza is a laboratory for structural characterization which operates the X-ray diffractometer Xenocs XEUSS 2.0, purchased thanks to the grant “Grandi Attrezzature d’Ateneo 2015”.
The instrument is capable of Small Angle X-Ray Scattering (SAXS), Wide Angle X-ray Scattering (WAXS) and Grazing Incidence Small Angle Scattering (GISAXS) experiments. These techniques are widely applicable for the characterization of matter (in solid, liquid, gel or thin film form) at the nano- and meso-scale.
The team who is in charge of the SAXSLab (Persone) is available to discuss potential experiments and to start collaborations in case of more demanding data analysis and interpretation.
The SAXSlab is located in the Department of Chemistry, Cannizzaro Building (Building CU014), Ground Floor, Room 058.
The SAXS/WAXS/GISAXS/GIWAXS platform of SAXSlab Sapienza is a Xeuss 2.0 HR P300K Q-Xoom (XENOCS) system with the following set-up:
- Genix3D micro-focus Cu Ka source with power 30W and collimation optics FOX3D single reflection;
- Beam collimation system with two modules of scatterless slits, having four independent blades with motorized opening;
- Sample chamber for measurements at reduced pressure (0.3 mbar) or in air (but with reduced sensitivity and q-range);
- Stage for several sample holders with motorized X, Y and Z translations and incident angle rotation for GISAXS;
- 2D detector Dectris Pilatus3 R 300K in vacuum for measurements SAXS/WAXS with motorized movement along Y to vary the sample-detector distance (from around 25 to 250 cm) and along an horizontal axis perpendicular to the incident beam for measurements with azimuth 180° or 90°;
- A second detector Pilatus3 R 100K for simultaneous WAXS, with accessible scattering angles 18°< 2theta < 46° (or, for a different sample position 24°< 2theta < 60°).
The system is programmable for simultaneous SAXS/WAXS acquisitions on a set of samples. Thanks to the detector motorized support data can be collected in several SAXS configurations. The presence of the two detectors enables an overall accessible q range 0.04 < q < 33 nm-1.
The instrument is controlled by a SPEC software with SPECFE user graphical interface, in Unix environment.
Data treatment and reduction are performed eith the software FOXTROT (from the collaboration between the XENOCS company and the French synchrothron Soleil).
