Abstract:
1. A transmission x-ray tube comprising: a. an end window hermetically sealed to a first end of a flexible coupling; b. a second end of the flexible coupling hermetically sealed to one end of an enclosure; c. a cathode including an electron emitter hermetically sealed to an opposite end of the enclosure; d. the electron emitter configured to emit electrons in an electron beam along an electron beam axis extending between the electron emitter and the window and through a hollow core of the flexible coupling; e. the window including a target material configured to produce x-rays in response to impinging electrons from the electron emitter; f. the window configured to allow the x-rays to be transmitted out of the enclosure through the window; and g. the window being selectively tiltable to selectively align a region of the window with the electron beam axis, and thus selectively position the region in the electron beam by tilting the window and the first end of the flexible coupling at an acute angle with respect to the electron beam axis.
