    摘要: An X-ray reflectometry apparatus comprises an X-ray source (1) configured to emit an incident X-ray beam directed onto a sample measuring position and an X-ray detector (2) configured to detect an X-ray beam (3) reflected from a surface of a selected sample (4) located in said sample measuring position and with a multiple sample holder (5) comprising an essentially horizontal one- or two-dimensional array of sample resting positions into which solid samples can be placed from above. A drive mechanism (6) moves the sample holder in one or two directions within a horizontal plane underneath the sample measuring position in order to place a selected sample (4) directly beneath the measuring position and a sample lift mechanism (7) has a vertically movable piston (8) located below the multiple sample holder (5) beneath the sample measuring position. When the sample lift mechanism (7) is activated, the piston (8) moves upwards against a bottom surface of the selected sample (4) or sample container (9) containing said selected sample (4), lifts the selected sample (4) or sample container (9) until it touches a stop (10) that keeps the sample (4) in the sample measuring position. When the sample lift mechanism (7) is deactivated, the piston (8) moves downwards and the sample (4) rests in its resting position. The device prevents signal cross talk to neighboring samples or to the sample holder, while also assuring an alignment which can be parallel to the incident beam.

    摘要: A method for operating an X-ray or neutron-optical system and beam stop comprising an X-ray or neutron source (1) from which corresponding radiation is guided as a primary beam (2) to a sample (4) under investigation, with an X-ray or neutron detector (6) for receiving radiation diffracted or scattered from the sample (4), wherein the source (1), the sample and the detector are disposed substantially on one line (=z-axis) and wherein a beam stop (5; 31; 41) is provided between the sample and the detector whose cross-sectional shape is adjusted to the cross-section of the primary beam is characterized in that the beam stop is disposed to be displaceable along the z-direction for optimum adjustment of the amounts of useful and interfering radiation impinging on the detector. This protects the detector from the influence of the primary beam while allowing a maximum amount of diffracted or scattered radiation to reach the detector, wherein the beam stop can be easily adjusted to temporally changing properties of the beam optics.
