Abstract:
1. An X-ray source, comprising a target configured to emit X-rays upon bombardment with an electron beam; an electron-beam-generator with a plurality of electron-beam sources which selectively emit electron beams that converge towards the target on target points along at least one line of a group consisting of one line and two lines along a surface of the target, the electron-beam-generator, comprising: a controller configured to control the electron-beam-generator by selectively switching activation of each electron emitter, and the controller is configured during operation to provide a positive electrical potential to the target and provide a negative electrical potential to at least one electron emitter of the array of electron emitters, and provide an electrical potential to the electrode device to achieve a predetermined one of a collimation or a deflection of electrons; and wherein the first substrate and the conductive substrate are configured as one of the following ways:
