X-ray diffractometer stage for in situ structural analysis of thin films


A theta-two theta x-ray diffractometer stage has been developed for in situ structural characterization of thin-film samples. This stage integrates an ultrahigh vacuum dc ion-beam thin-film sample preparation chamber with the Siemens D500 x-ray diffractometer. In vacuo sample translation and manipulation is provided. The stage incorporates resistive heating to 900 K and liquid nitrogen cooling to 150 K. The sample theta rotation is transmitted into the vacuum chamber by a rotary feedthrough. X rays enter the vacuum chamber through a beryllium window with allowed reflection angles from 0 to +168° two-theta.
