There are three SAXS set-ups (SAXS-Cu, MODIX, PADIX) which differ according to the radiation wavelength and the accessible scattering wavevectors range.
1. SAXS-Cu
Instrumental: GENIX3D (Cu radiation) ultra low divergence system (Xenocs corp), Motorized hybrid “scatterless” slits, intensity measurement diode, MAR345s Image Plate detector (MarXperts GmbH)
D = 1620 mm, 4 mm diameter beamstop, dmax = 80 nm ↔ Qmin = 8.10-3 Å-1
2. MODIX
Simultaneous small and wide angle scattering measurements with Molybdenum radiation, well-adapted for measuring strong absorbing samples.
Instrumental : Molybdenum (Mo) rotating anode generator, multilayer mirrors optics, hybrid “scatterless” slits, motorized autosampler, removable beamstop (two different size), intensity measurement diode, MAR345 image-plate detector.
Accessible scattering wavevector domains :
- Qmin = 3.10-2 Å-1, Qmax = 3 Å-1 (large beamstop with diode)
- Qmin = 1.5.10 -2 Å-1, Qmax = 3 Å-1 (small beamstop)
3. PADIX
Instrumental : Copper (Cu) rotating anode microfocus generator (Rigaku Micromax007), multilayer mirrors optics, sample translation and rotation motorized stages, CCD (MarCCD) and hybrid-pixel (XPADS70) detectors.
Accessible Q wavevectors domain : Qmin = 2.10-2 Å-1, Qmax = 5.10-1 Å-1 ↔ dmin = 1.25 nm, dmax = 31 nm
