摘要：
The present disclosure relates to a field emission X-ray tube apparatus for facilitating cathode replacement, and more particularly, to a field emission X-ray tube apparatus for facilitating cathode replacement in which gates and cathodes are easily arranged through a joining member and a rotation preventing guide when gates and insulating spacers are rotated and joined with the cathodes while the cathodes and respective gates maintain electrical insulation, thereby easily replacing the cathodes.
