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： For maintaining a monolayer of scandium which is necessary for a satisfactory emission on the surface of a scandate cathode, at least the top layer of the cathode is provided with scandium coated with a scandium oxide film. Even after repeated ion bombardment the emission is found to recover up to approximately 90% of the initial value at a current density of ca. 100 A/cm².

摘要： A method of manufacturing a scandate dispenser cathode having a matrix at least the top layer of which at the surface consists substantially of tungsten (W) and scandium oxide (Sc 2 O 3 ) and with emitter material in or below said matrix. If said method comprises the following steps:
a) compressing a porous plug of tungsten powder;
b) heating said plug in a non-reactive atmosphere and in contact with scandium to above the melting temperature of scandium;
c) cooling the plug in a hydrogen (H 2 ) atmosphere;
d) pulverizing the plug to fragments;
e) heating said fragments to approximately 800°C and firing them at this temperature for a few to a few tens of minutes in a hydrogen atmosphere;
f) grinding the fragments to scandium hydride-tungsten powder (ScH 2 /W);
g) compressing a matrix or a top layer on a matrix of pure tungsten from said ScH 2 /W powder or from a mixture of this powder with tungsten powder;
h) sintering and cooling the said matrix;
i) bringing emissive material in the cathode, a scandate dispenser cathode is obtained the recovery of which after ion bonbardment occurs better than in cathodes having Sc 2 O 3 . The scandium is also distributed more homogeneously in the cathode than in cathodes having Sc 2 O 3 grains.
