Publication number: 20200365363Abstract: The present invention relates to a portable X-ray tube, and more particularly, to a portable X-ray tube capable of miniaturization and weight reduction by reducing the structural volume of the X-ray tube by installing cathodes in the same direction together with the fixed anode. The portable X-ray tube comprises: an anode portion comprising an anode heat sink for conducting and dissipating heat transferred through the anode, an anode formed on the upper part of the anode heat sink, and an anode target formed on the inclined surface of the upper end of the anode; a cathode portion installed in parallel with the anode through the installation hole of the cathode portion formed in the anode heat sink; and a vacuum bulb fixed to the heat sink to seal the anode portion and the cathode portion with a vacuum; wherein the X-rays emitted through the anode target are irradiated to the upward direction as the installation direction of the anode.Type: ApplicationFiled: August 4, 2017Publication date: November 19, 2020Applicant: XL CO., LTD.Inventor: Rae Jun PARK

Publication number: 20160260573Abstract: The present invention relates to an X-ray tube with non-evaporable getters disposed therein for maintaining a degree of vacuum sufficient to operate the X-ray tube. The present invention provides a fixed-anode X-ray tube and a rotating-anode X-ray tube in which non-evaporable getters are disposed. The X-ray tubes, even when rated power is introduced without an aging process, can perform gas adsorption sufficiently and stably during operation, despite gases that can be generated by the filament and the cathode focusing cap and gases that can be generated by the target.Type: ApplicationFiled: May 18, 2016Publication date: September 8, 2016Applicant: XL CO., LTD.Inventor: Rae Jun Park
