A vacuum electron tube comprises at least one electron-emitting cathode and at least one anode arranged in a vacuum chamber, the cathode having a planar structure comprising a substrate comprising a conductive material, a plurality of nanotube or nanowire elements electrically insulated from the substrate, the longitudinal axis of the nanotube or nanowire elements substantially parallel to the plane of the substrate, and at least one first connector electrically linked to at least one nanotube or nanowire element so as to be able to apply a first electrical potential to the nanowire or nanotube element.

Vacuum electron tube with planar cathode based on nanotubes or nanowires

An x-ray generator tube comprises a vacuum chamber with a cathode and an anode, the cathode and anode placed in the vacuum chamber, the cathode emits an electron beam in the direction of the anode, the anode includes a target emitting x-rays when it is struck by the electron beam, and the x-rays propagate out of the vacuum chamber by passing through the wall of the chamber via a diamond-based transmission window. According to the invention, a diamond-based x-ray sensor is integrated into the diamond-based transmission window.
