ROTATING ANODE OF X-RAY TUBE Russian patent published in 1994 - IPC

FIELD: X-ray engineering. SUBSTANCE: anode has a disk made of heavy metal or alloy with blind spots. The disk is provided with thin-wall annular central bushing, which is embraced with graphite substrate. There are through holes in the substrate. Any hole is disposed in opposite to corresponding blind hole in the disk. Thin-wall sleeves are soldered into the through holes. Value of depth of the bottoms of the sleeves into the body of the disk is larger than thickness of bottom of the sleeve. The sleeves are made of material which has thermal expansion coefficient being close to thermal expansion coefficient of material from which the disk is made. EFFECT: improved efficiency. 2 cl, 2 dwg
