A door configuration, which improves the operating and locking mechanism and facilitates construction and handling, comprising a door having a sliding door disposed on a casement such that it can be slidably displaced and the casement can he pivoted about an axis relative to a main frame. A lock is provided for locking and unlocking the casement with respect to the main frame, and an operating element is disposed on the sliding door, which can be moved with the sliding door and can be switched between a first position and a second position, wherein, in the first position, the operating element does not obstruct movement of the sliding door on the casement, and, in the second position, the operating element engages with the latch or a carrier, such that, when the casement is closed, the latch is operated when the sliding door is moved.

An X-ray optical element () with a Soller slit comprising several lamellas for collimating an X-ray beam with respect to the direction of the axis () of the Soller slit, and a further collimator for delimiting an X-ray (), wherein the further collimator is rigidly connected to the Soller slit () during operation, is characterized in that the X-ray beam () delimited by the further collimator intersects the axis () of the Soller slit within the Soller slit, and the direction of the X-ray beam () subtends an angle &#x3b1;&#x2267;10&#xb0; with respect to the axis () of the Soller slit. An X-ray optical element () with a Soller slit () and a further collimator is thereby realized, which permits automatic change between the Soller slit () and the further collimator.

A safety housing () for an X-ray apparatus, comprises a working chamber () which can accommodate X-ray apparatus protection elements (-), in particular lead-containing walls and/or lead glass panes, which are impermeable to X-rays and which surround the working chamber () and at least one door () for opening and closing an access () to the working chamber () of the safety housing (), wherein the door () has at least one door protection element (), in particular a lead glass pane, which is impermeable to X-ray radiation, wherein the at least one door protection element () can completely cover the access to the working chamber (), and wherein the door () can be pivoted about an axis S relative to a main frame () of the safety housing (). At least one door protection element (-) of the door () is formed on one sliding door (), the sliding door () being disposed on a casement () of the door () such that it can be displaced in a direction V, and the casement () of the door () can be pivoted about the axis S relative to the main frame (). The amount of space that is required in front of the access to the working chamber is thereby reduced.

An X-ray diffractometer comprising an X-ray source ( ) from which X-rays are guided to a sample ( ) to be investigated, an X-ray detector ( ) for receiving X-rays diffracted or scattered from or reflected by the sample ( ), and a goniometer for adjustment of sequential relative angular positions between the X-ray source ( ), the sample ( ) and the X-ray detector ( ) for detecting X-ray diffraction lines, X-ray scattered signals or X-ray reflectograms of the sample ( ) to be investigated, wherein the X-rays can be guided at least sectionally along different optical paths, is characterized in that the X-rays can be guided from a position to a position along n&gE;2 different switchable optical paths, wherein the different optical paths are rigidly disposed relative to each other between position and position and form a unit ( ), wherein the sample ( ) assumes either position or position and wherein the switching over between the different optical paths can be effected by turning the unit ( ) relative to the sample ( ) about the sample position. Due to its considerably more compact structure compared to conventional arrangements, the inventive arrangement requires considerably less space while maintaining full relative motion of the parts, wherein the arrangement permits omission of expensive components, in particular detectors and associated measurement electronics.
