X-RAY TUBE REVOLVING ANODE Russian patent published in 1998 - IPC

Abstract RU 2117358 C1

FIELD: X-ray engineering; large X-ray tubes used for medical diagnostics. SUBSTANCE: uniform heating of substrate and reduced stresses in substrate and target are attained by using variable geometry and/or material composition and properties of material. Substrate layer thickness H in vicinity of focusing track is minimum (E1H22

/E2)0,5 and maximum 10(E1H21
/E2)0,5, where H1 is target thickness, E1 and E2 are Young moduli of target and substrate layer, respectively; width of this region amounts to at least size of focusing track. EFFECT: improved service life and reliability of revolving anode. 7 cl, 2 dwg
