A line number application is formed in which the focal trajectory of the electron beam is drawn. Normally, the difference in diameter between the hole la of the target hole and the support part 2a of the support shaft 2 must be 10 μm or less, and it must be kept in a very fine cylindrical fitting shape. The question of the Machine Kado Neja, Q'? Because the material is brittle, the distance between the graphite metal targets and the target hole diameter changes due to misalignment of the parts during planning and vibration during use, resulting in It is easy to cause looseness.

To fill the molybdenum powder, when assembling the Turkera) l and the support shaft 2, apply an ink containing molybdenum powder mixed with a solvent such as diethylene brecol monoethyl ether acetate to the mounting hole 1at or the support part 2a in advance. This can be easily achieved by assembling the line before it completely changes. Molybdenum has good adhesion to graphite, and is subsequently used in the manufacturing process of X-ray tubes.
・During ψ operation, the distance between the mounting hole 1a and the support part 2a is 1,000 to 1,300°C H'Q3 m for several hours.
1tl 1:jj Since the molybdenum powder drips down, the molybdenum powder is easily sintered and fixed in the mounting hole 1a and the support portion 2a. of course,
Since molybdenum has extremely high heat resistance, it is not lost by heating as described above. Molybdenum powder has a diameter of about 1 μm, and such molybdenum powder is filled between the mounting hole 1a and the support portion 2a to fill the gap between them. By completely filling them, both can be fixed in a strong position. Also,
The surface of the inner wall of the attachment hole la made of graphite is made of a film of gold molybdenum, so that the hole diameter of the target will not change easily due to chafing during use.
