HIGH PERFORMANCE X-RAY TARGET

摘要

A brazed X-ray target (60) includes a metallic cap (64) and a graphite back (62) including a nonlinear record groove attached thereto along a stepped surface. An upper corner joint of the stepped surface is distanced from a cap outer edge (68) and a focal track (82) where the maximum heat is generated during use of the target. The graphite back is extended outward toward the cap outer edge to increase a thermal storage of the graphite, and a recess (74) is formed into the cap to maintain a selected moment of inertia of the target and thereby maintain the rotordynamics of a given X-ray tube.
