An X-ray tube including an envelope enclosing a flat-edged anode disc rotatable and axially reciprocable and further enclosing an electron beam source for projecting electrons along a beam axis toward the edge of the anode disc. The beam source is disposed to direct its beam at an acute angle of incidence to the edge of the anode disc and produce X-rays which are transmitted through a window in the envelope.
