FIELD: X-ray engineering; medicine; diagnostics. SUBSTANCE: hyperbolic-shape dent is made in center of substrate, its depth making up 0.3-0.7 of substrate thickness and its diameter, 0.2-0.5 of that of substrate. EFFECT: improved service life and reliability of rotating anode of high-power X-ray tube due to provision for uniform heating of graphite substrate and reduced stretching forces in it. |
