、Ｘ線管。 It consists of an anode part and a cathode part surrounded by a single envelope, and a high voltage applied between the two electrodes accelerates and focuses thermionic electrons from the filament of the cathode part, and accelerates and focuses them on the disk of the anode part. An X-ray tube that generates X-rays by colliding fast electrons has a third electrode that is placed between two electrodes and is made of a flat plate with a hole in the center, and the potential of the third electrode is An X-ray tube characterized in that the X-ray tube is maintained at a potential at that position when a predetermined high voltage is applied between an anode and a cathode, or at a potential on the positive side of the potential.
