There are mainly five parts of the SAXS setup i) Sample Stage: Solid Sample on different substrate as well as liquid sample in capillary tube can be mounted on the 1st goniometer. ii) Vacuum path: 3.5 meters long vacuum path connected with two rotary pumps to minimize the air scattering. iii) Vacuum integrated beam stopper: A motor controlled Pb beam stopper (10 mm diameter) inside the vacuum chamber to stop the direct beam before it hits the kapton window, iv) Ion chamber: for the alignment of the sample for SAXS and GISAXS geometry. v) Detector: To collect the SAXS pattern, a 1M Pilatus 2D detector placed just after the evacuated chamber. vi) The sample to detector distance ~ 3800 mm. At λ = 1.223 Å, the available Δqz = 0.24 Å-1 and Δqy = 0.18 Å-1. |
