Jet cooled x-ray tube window

An x-ray tube comprising:

• a housing unit;
• a cathode coupled within said housing unit and generating an electron beam;
• an anode coupled within said housing unit and receiving said electron beam and generating x-rays that are directed through an x-ray tube window;
• and
• an x-ray tube window cooling assembly comprising;
• an electron collector body coupled to said x-ray tube window and having a first coolant circuit comprising;
• a coolant inlet and a coolant outlet, said coolant outlet directing coolant at a reflection surface on the x-ray tube, opposite that of an x-ray tube window surface, to reflect said coolant off said reflection surface as to impinge upon and cool said x-ray tube window.

A method of operating an x-ray generating device comprising:

• generating an electron beam;
• directing said electron beam at impinge upon an anode target to generate x-rays;
• directing said x-rays through an x-ray tube window increasing temperature of the x-ray tube window;
• and
• directing coolant at a reflection surface on the x-ray tube, opposite that of an x-ray tube window surface, to reflect said coolant off said reflection surface as to impinge upon and cool the x-ray tube window, via a first cooling circuit.
