Zusammenfassung:An electron emission source of an X-ray device according to a disclosed present invention comprises: a source part that emits electrons in both directions; an electron emission source comprising a gate part comprising the gate part that extracts electrons emitted from the source part in both directions by comprising a pair of gate members facing each other with the source part interposed therebetween; and an anode part that generates X-rays by collision with the electrons emitted from the electron emission source. According to the configuration, an output of the emitted electrons can be improved, and a highly efficient electron emission is enabled. 개시된 본 발명에 의한 엑스레이장치의 전자방출 소스는, 전자를 양방향으로 방출하는 소스부 및 소스부를 사이에 두고 상호 마주하는 한 쌍의 게이트부재를 포함하여 소스부로부터 양방향으로 방출되는 전자를 추출하는 게이트부를 포함하는 게이트부를 포함하는 전자방출 소스 및, 전자방출 소스로부터 방출된 전자와의 충돌에 의해 엑스레이를 발생시키는 애노드부를 포함한다. 이러한 구성에 의하면, 방출되는 전자의 출력을 향상시킬 수 있어, 고효율의 전자방출이 가능하다.
