摘要： In an X-ray tube, particularly for the detection of elements having a low atomic number by X-ray spectral analysis, an anode support (4) is on the target side provided with a layer (7) of scandium. The scandium disc is provided on the anode by adhesion via an intermediate layer (8), preferably of chromium. In a relection tube, the anode block supporting the intermediate layer and the scandium layer is preferably made of silver or copper. In a transmission tube, the scandium is provided on a beryllium disc which acts as intermediate layer and as an exit window (6).

摘要： The separating layer (18) between the luminescent layer (16) and the photocathode (20) of the entrance screen (10) in an X-ray image intensifier tube (1) is formed by a layer which has a suitable optical transmission, a suitable chemical inertia, a suitable tightness and a strongly bridging character and which is deposited by means of a plasma CVD technique, so that all requirements to be imposed on a separating layer can be satisfied without causing a substantial loss of efficiency. By variation of the material composition, measured across the thickness of the layer, an optimum optical transition can be realized between the luminescent layer and the photocathode.

摘要： An anode of an X-ray tube, particularly for X-ray analysis, comprises at least two successive layers (7, 8 or 11, 10 or 13, 12) of anode material. A first layer (7, 11, 12) thereof consists mainly of an element having a comparatively low atomic number, such as scandium or chronium, whilst a further layer (8, 10, 13) consists mainly of an element having a comparatively high atomic number, such as molybdenum, tungsten or uranium. Forthe selection of a desired radiation spectrum, the tube voltage is either adapted to the radiation and absorption properties of the anode material or can be switched over between several values. Upon the first layer a layer of for example beryllium can additionally be mounted.
