Description

전자총 전극 구조체Electron gun electrode structure

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도, 제2도는 본 발명의 일실시예를 도시하는 폐색 통형 전극의 상면도와 보조 전극의 상면도. 제3도는 이것을 조합시켜 주전자 렌즈를 구성한 전극체의 측단면도.1 and 2 are top views of an occluded cylindrical electrode and an auxiliary electrode of an embodiment of the present invention. 3 is a side cross-sectional view of the electrode body in which the kettle lens is combined to form a kettle lens.

Claims (1)

주전자 렌즈를 구성하는 제1의 폐색면을 구비하여 서로 대향하는 한쌍의 폐색 통형 전극을 가지는 전자총 전극 구조체에 있어서,In the electron gun electrode structure having a pair of closed cylindrical electrodes facing each other and having a first closed surface constituting the kettle lens, 상기 제1폐색면을 소정거리 후퇴시킴에 의해 개공 이심거리 S의 1.05내지 1.30배의 구경 Do을 갖고 인라인 배열된 3개의 제1개공을 서로 중첩시켜 꿰뚫어 통하는 구멍 형태의 凹부를 형성하고, 그 하면인 제2폐색면으로 제1개공과 동축을 유지하며, 상기 개공 이심거리 S보다 작은 개공 구경 D1을 갖는 독립의 돌출형 둘레가 붙어 있는 제2개공을 설치하며, 상기 한싸의 폐색 통형 전극의 집속전압이 인가되는 전극에 대향하는 전극내에 양 외측이 원형의 개공을 가지고, 중앙이 인라인 개공 배열방향으로 긴 변을 갖는 직사각형 구멍을 가지는 보조 전극을 설치한 것을 특징으로 하는 전자총 전극 구조체.By retracting the first occluded surface by a predetermined distance, a three-dimensional opening having an aperture Do of 1.05 to 1.30 times the opening eccentric distance S and overlapping three first holes arranged in in-line are formed to form a hole in the form of a hole. The second occluded surface is coaxial with the first opening, and installs a second opening with an independent protruding circumference having an opening aperture D1 smaller than the opening eccentric distance S. An electron gun electrode structure, wherein an auxiliary electrode having circular holes in both outer sides thereof and a rectangular hole having a long side in the center of the in-line opening arrangement direction is provided in an electrode facing the electrode to which a voltage is applied. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
