X-RAY TUBE FOR GENERATING SOFT X-RAYS

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 layer is provided on the support by adhesion via an intermediate layer (8), preferably of chromium. In a reflection tube, the anode support for 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).
