Abstract
Electrons can rebound from an x-ray tube target, causing electrical-charge build-up on an inside of the x-ray tube. The charge build-up can increase voltage gradients inside of the x-ray tube, resulting in arcing failure of the x-ray tube. Also, the electrical charge can build unevenly on internal walls of the x-ray tube, causing an undesirable shift of the electron-beam. An x-ray tube (or) with multiple protrusions () on an interior wall of a drift-tube () can reduce this electrical-charge build-up. The protrusions () can reflect stray electrons back to the anode target (), thus suppressing backscatter. Each protrusion () can have a peak () extending into the hole (), and receding to a base () farther from the electron-beam, on an entry-side () nearest the drift-tube-entry () and on an exit-side () nearest the drift-tube-exit ().
