Abstract
A coolant oil from an x-ray tube (14) is circulated through a heat exchanger (18) to reduce its temperature. More specifically, at least one hot coolant fluid receiving aperture (30) is defined adajcent an end of a suction tube 32) in an upper most portion of a horn portion (16) surrounding a cathode termination assembly. Bubblers (42) of gas in the fluid which could be ionized by electrical fields inside the x-ray tube housing causing x-ray tube current irregularities and corresponding x-ray tube output irregularities are drawn into the suction tube aperture. A debubbler (38) removes bubbles from the cooled coolant fluid before it is returned into an anode horn portion (20) of the x-ray tube. Alternately, the bubbles may be reabsorbed, dissolved, or homogenized by the action of the heat exchanger and pump. The coolant fluid passes through a central portion (24) of the x-ray tube absorbing heat and back to the cathode horn portion.
