Description

비점수차를 감소시키는 평형 렌즈립을 갖춘 전자총
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 신규의 3-비임 인-라인(In-line)형 전자총의 종단면도.
제2도, 제3도는 제1도에 도시된 전자총의 전자렌즈 전극의 직교면에 집속계를 도시한 단면도.

Claims (1)

  1. 저 전압 전극(18)과 고 전압 전극(20)으로 구성된 전자총에서, 상기 이 두 전극사이에 전자총의 동작시정전 집속계가 성립되는데, 상기 두 전극의 각각은 상기 전극의 다른 부분에 직면하는 플로워에세 인-라인 개구(32,38)를 가진 연장된 터브(26,36)를 포함하고, 상기 전극의 각 개구들은 상기 전극의 다른 부분으로부터 떨어진 방향에 있는 외면 개구들로부터 연장한 튜블러 립(34,40)을 가지며, 상기 전극의 터브는 저 전압 전극에서 비임-집중 비 점수차를 그리고 고전압 전극에서는 비임-분산 비점수차를 만들어 내는 세-비임인-라인 전자총(10)에서,
    저 전압 전극 립(34)의 길이가 고전압 전극 립(40) 길이보다 더 길게 설계하여 그들 길이의 비가 규정된 양에 의한 고전압 전극에 비점수차에 비례하여 저전 압전극에 비 점수차를 감소시켜 규정된 설계치에 집속계의 비점수차를 조절하는 것을 특징으로 하는 비 점수차를 감소시키는 균형잡인 렌즈 립을 가지는 전자총.
