(a) The GISAXS experimental setup and the coordinate system used in HipGISAXS. The incoming X-ray beam is propagated along the wavevector at an incidence angle αi with respect to the sample axes as shown. A scattered (outgoing) beam is also shown, propagating toward the area detector. (b), (c) Illustrations of the sample tilt and in-plane rotation angles, respectively. |
