Abstract
An x-ray tube assembly ( ) includes a housing ( ) and an insert frame ( ) supported within the housing ( ), such that the insert frame ( ) defines a substantially evacuated envelope in which cathode ( ) and anode ( ) assemblies operate to produce x-rays. An x-ray transmissive window assembly ( ) extends between and in a fluid-tight relationship with the housing ( ) and the insert frame ( ). The window assembly ( ) includes an insert window ( ) brazed to the insert frame ( ), a top plate ( ), which is connected to and substantially surrounded by a flange ( ), where the flange ( ) is fastened to the x-ray tube housing ( ). An annular side plate ( ) is connected to a fluid-tight relationship with both the insert frame/window interface ( ) and the flange ( ). The window assembly ( ) cools the window through enhanced heat transfer while preventing housing coolant from contacting the insert window ( ), thereby eliminating coolant carbonization on the window ( ) and enhancing x-ray beam quality.
