Document Type and Number:
WIPO Patent Application WO/2020/111819
Kind Code:
A1
Abstract:
The present invention relates to a small X-ray tube comprising a heat emitting cap. The small X-ray tube comprises: a filament for discharging electrons when voltage is applied thereto; a target for receiving the electrons discharged from the filament and emitting an X-ray; a body which is made of a ceramic material and has one side connected to the filament and the other side connected to the target, thereby forming an airtight state between the filament and the target; an extraction pipe which extends through the target and extracts internal air of the body to form an airtight state of the body; and a cap which is in close contact with the target on the opposite side of the body and surrounds the end portion of the extraction pipe.
