Abstract
A rotary anode X-ray tube wherein the anode carries the high voltage during operation; to achieve shorter acceleration times of the rotor, an insulator is provided between the rotor and the anode disc so that only a minimum air gap is required between the rotor and the stator.
Claims7
An X-ray tube comprising an envelope, and, within the envelope, a rotary anode including a shaft adapted for connection to a high potential, a rotor concentrically arranged around a portion of said shaft, an insulating member connecting the inner wall of said rotor to said shaft portion, and a stator separated from said rotor by a minimum gap.
