A monochromatic beam was obtained by means of a Si(111) double crystal monochromator. Experiments were performed at the Ca K-edge in transmission mode.
To obtain details of the microscopic structure of the elastomers, we performed temperature dependent X-ray diffraction measurements at beamline BL15 of the Kyushu Synchrotron Light Research Center (Japan), where we used 8.00 keV X-rays (wavelength = 1.550 A) filtered by a double crystal monochromator and an image plate system with 4096 x 8040 pixels and 50 [micro]m resolution.
In operation, the beam line is passed through an undulator and then a crystal monochromator. Optical output is then passed through a zone plate objective lens and focused through an aperture onto the sample, which is raster scanned.
