1. An X-ray scattering apparatus (10), comprising:
a sample holder (16) for aligning and/or orienting a sample (17) to be analyzed by X-ray scattering;
a first X-ray beam delivery system (12) comprising a first X-ray source (18) and a first monochromator (20) and being arranged upstream of the sample holder (16) for generating and directing a first X-ray beam (22) along a beam path in a propagation direction (Y) towards the sample holder (16);
a distal X-ray detector (14) arranged downstream of the sample holder (16) and being movable, in particular in a motorized way, along the propagation direction (Y) such as to detect the first X-ray beam (22) and X-rays scattered at different scattering angles from the sample (17);
wherein the first X-ray beam delivery system (12) is configured to focus the first X-ray beam (22) onto a focal spot on or near the distal X-ray detector (14) when placed at its largest distance from the sample holder (16) or to produce a parallel beam,
characterized in that the X-ray scattering apparatus (10) further comprises a second X-ray beam delivery system (28) configured to focus a second X-ray beam (42) onto a focal spot on or near the sample holder (16);
wherein the second X-ray beam delivery system (28) comprises a second X-ray source (30) and a second monochromator (32); and
further comprising an insertion module (36) configured to move the second X-ray beam delivery system (28) into the first X-ray beam (22) at a position upstream of the sample holder (16).
