An x-ray tube ( ) includes an evacuated envelope ( ), a cathode assembly ( ) located in the evacuated envelope and a disk shaped anode assembly ( ) located in the evacuated envelope in operative relationship with the cathode assembly for generating x-rays ( ). The anode assembly includes an axis of rotation ( ) and a target substrate ( ) facing the cathode assembly. A heat pipe ( ) is located within the anode assembly ( ). The heat pipe is comprised of an evacuated shell ( ) and is vacuum sealed at a first end ( ) of the shell and at a second end ( ). A material ( ) within the shell is a working fluid for the heat pipe at x-ray tube operating conditions. A porous wick ( ) is located within the shell and the wick has a length extending from the first end ( ) of the shell to the second end ( ) of the shell. A shield ( ) is attached to the wick to reduce working fluid loss out of the wick during x-ray tube operation.
