Abstract: Embodiments included herein are directed towards an apparatus and method for manufacturing an electrical cooling apparatus. The method may include forming a first entirely solid metal plate to generate an enclosure. The method may also include affixing a bottom metal plate to the first entirely solid metal plate, the bottom metal plate may define a channel system. The bottom metal plate may include one or more inlet openings into the channel system, where the one or more inlet openings are configured to allow coolant to enter or exit the channel system.

Abstract: A limiting device (9) for electromagnetic radiation (3; 5; 7) includes an essentially flat beam cross-section limiter (10) which partly or completely encloses at least one passage aperture (12; 13) for beams (5; 7) and is constructed so that it also includes at least one second beam cross-section limiter (14) which, in the active position, constitutes at least one longitudinal component extending at an angle to the first beam cross-section limiter (10).

Abstract: A device (1) for the examination of samples by means of X-rays or the like, the device being provided with at least one X-ray source which can be mounted in an exchangeable constructional unit (5) and with an analysis chamber (4) which encloses an exit window (6) of the X-ray source in its operative position and whereto the constructional unit (5) with the X-ray source can be attached. The device is constructed in such a manner that respective, matching parts (9; 10) of a safety system (7) are associated with the analysis chamber (4) and the constructional unit (5) with the X-ray source.
