X-radiator with constraint-cooled rotating anode

An X-ray radiator comprising:

• an X-ray tube having a vacuum housing with an anode and a cathode rigidly mounted in said vacuum housing, said cathode emitting an electron beam;
• a coolant container surrounding said X-ray tube and filled with a coolant;
• a radiation protection housing surrounding said coolant container;
• means for mounting said X-ray tube and said coolant container in said radiation protection housing for permitting rotation of said X-ray tube and said coolant container relative to said radiation protection housing;
• drive means for rotating at least one of said X-ray tube and said coolant container in said radiation protection housing around a rotational axis during operation of said X-ray tube, said X-ray tube emitting an X-ray beam during said operation;
• and
• deflection means, disposed inside said radiation protection housing and mounted stationarily relative to said radiation protection housing, for deflecting said electron beam onto a stationary focal spot on said anode.
