Claim 5:
6. An x-ray apparatus, comprising:
a vacuum chamber having a wall and a window in said wall to allow exit of x-rays with a vacuum existing in said vacuum chamber;
a cathode assembly housed within said vacuum chamber, wherein said cathode assembly includes at least four non-contiguous filaments;
a liquid cooled window anode that incorporates a cooling path in which sides of the cooling path provide structural support for the window to keep a vacuum in said chamber;
a power supply connected between said cathode assembly and window anode, whereby free electrons are accelerated in their flow from said cathode assembly to said window anode within said vacuum chamber;
said window anode containing a thin layer of a target material that has an atomic number equal to or greater than 73, whereby the thin layer is of sufficient thickness that a majority of electrons reaching the window anode will be absorbed by said thin layer and whereby the thin layer is of sufficient thinness that resulting x-rays can exit the other side of said thin layer and thereafter exit from the window anode through the window; and
wherein said cooling path is between a base plate with stepped surfaces and curved segments coated with the target material.
