Abstract
For developing electron microscopes mounted with a single-atom electron source, we constructed a practical gun chamber of an extreme high vacuum (XHV), and demonstrated excellent characteristics of its emission beams; the stable beam with the current fluctuation of ̃0.8 % was observed at the total current of 20 nA in the XHV of 1 × 10-9 Pa. © 2008 The Surface Science Society of Japan.
