Abstract: 【課題】 電子放出源から放出される電子(電子ビーム)の位置をエクストラクタで直接感知することによって、マイクロカラムのエクストラクタ孔及び電子放出源の整列をより容易に且つ簡便に行うことができ、しかも自動整列を可能にすることによって、長時間電子カラムを使用しても、正確な整列補正を容易に且つ自動に行うことができるエクストラクタ及びこれらを整列する方法を提供する。
【解決手段】 本発明によるマイクロカラムに用いられるエクストラクタは、電子放出源から放出された電子ビームの電子を電気的に導通させる複数の感知領域と、電子の流れを遮断する絶縁体又は電子の流れを減少させる低濃度ドープ半導体よりなり、前記各々の感知領域を分割する絶縁部と、を備える。-

Abstract: A method for detecting electron beam filament wear in an electron beam source, the method comprising the steps of: enlarging a beam spot emanating from the electron beam source on a work table to a predetermined minimum size, capturing an image of the beam spot on the work table by a camera, comparing the captured image of the beam spot with a reference image, and detecting filament wear if the captured image is deviating more than a predetermined value from the reference image.
