Abstract

The present invention relates to an X-ray source having a carbon nano-tube (CNT) yarn, an X-ray generating system and a manufacturing method thereof. The present invention is to restrain damage to the carbon nano-tube yarn due to the stress acting on the carbon nano-tube yarn in the process of generating an X-ray. The X-ray source according to the present invention includes: a carbon nano-tube yarn having an outer peripheral surface; and an insulating protection layer formed on the outer peripheral surface of the carbon nano-tube yarn. By forming such an insulating protection layer on the carbon nano-tube yarn, it is possible to restrain the damage such as un-twisted portions due to a high current, arcing or stress acting on the carbon nano-tube yarn in the process of generating an X-ray, improve the field emission effect of the carbon nano-tube yarn, and extend the lifespan thereof.
