Abstract
A vacuum-tight window construction for the passage of X-ray and similar penetrating radiation, the edge of the window having the shape of a tube and being tightly secured with a tube-shaped frame. The connection between the window and the frame is effected by a press-fit combination of three tube-shaped parts one into the other. One part is the tubular edge of the window, the second part is the edge of the frame, and the third part is an additional ring, the materials being selected such that the coefficient of thermal expansion of the outermost part is lower than that of the part disposed in the middle, and that of the innermost part is at least equal to that of the outermost part and less than that of the center part. The outermost and innermost parts can be composed of steel, and the middle part of pure or alloyed aluminum.
