- Abstract
- The present disclosure relates to an electric field emission x-ray tube apparatus equipped with a built-in getter, and more particularly, to an electric field emission x-ray tube apparatus equipped with a built-in getter that makes it possible to reduce the size of an x-ray tube by forming a stacked structure, with electric insulation and predetermined gaps maintained for each electrode, by manufacturing an x-ray tube having a stacked structure by inserting insulating spacers (for example, ceramic) between an exhausting port, a cathode, a gate, a focusing electrode, and an anode and bonding them with an adhesive substance, and then inserting a spacer between a field emitter on a cathode substrate and a gate hole connected with a gate electrode.
