Title:
COLD CATHODE ELECTRON SOURCE AND X-RAY GENERATOR EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2019/244874
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a modular structure for an X-ray source which allows for the replacement of a cold cathode electron source, thereby facilitating the production and maintenance of an X-ray source that uses a cold cathode electron source. An X-ray generator according to an aspect of the present invention comprises: a vacuum container having an opening; an anode at least a portion of which is located inside the vacuum container; a flange which is detachably attached to the vacuum container and secured to the vacuum container to close the opening thereof; and a cathode secured to the flange and including a cold cathode electron source located inside the vacuum container. This makes it possible to easily and replace just a cathode section.
