  • X-ray tube and X-ray generation device
    Patent number: 10999918
    Abstract: An X-ray tube, including: an envelope (11) that holds inside thereof at a predetermined pressure; a filament (12) for emitting electrons and a focus electrode (13) provided in the envelope: and a target (15) for generating X-ray provided in the envelope facing to the filament (12) and the focus electrode (13), wherein the envelope (11) has an envelope body (11a) and an X-ray window portion (16) having a higher X-rays transmissivity and a higher electric conductivity than the envelope body (11a), when the X-ray window portion (16) or the anode (14) is set to a lower electric potential than both of an electric potential of the anode (14) or the X-ray window portion (16) and an electric potential of the filament (12) and the focus electrode (13), detection of at least one of an ion current (Ii) or an electron current (Ie) through the X-ray window portion (16) or the anode (14) is possible.
