摘要：
The present invention relates to a radiation generating tube. The radiation generating tube includes an envelope including an insulating tubular member having at least two openings, a cathode connected to one of the openings of the insulating tubular member, and an anode connected to the other of the openings of the insulating tubular member. At least one of the cathode and the anode and the insulating tubular member are bonded at a bonded portion with an electrically conductive bonding member; and the bonded portion bonded with the electrically conductive bonding member is coated with a dielectric layer.
