X-RAY SOURCE COMPRISING CNT YARN FOR BRACHY THERAPY AND X-RAY EMITTING APPARATUS USING THE SAME

摘要

The present invention relates to an X-ray source using a carbon nanotube (CNT) yarn applying filtrated arc deposition. The present invention further relates to an X-ray generating device using the same. More specifically, the present invention relates to an X-ray source using a CNT yarn, which comprises: the CNT yarn of which negative potential (HV-) is applied so as to function as a negative electrode part and which emits electrons through an electron emission surface provided on one end part; and a vacuum case which includes the CNT yarn therein and keeps an interior thereof in a vacuum state. In addition, in the vacuum case, a metal window is formed on a position facing the electron emission surface, and a metal coating layer functioning as a positive electrode part is additionally formed, as positive potential (HV+) is applied to a surface of the metal window.
