Abstract(in English) | An electron gun for high resolution 19" CDT has been developed, by using improved "CLEAR GUN" design. To avoid cut off uniformity and cathode loading problem, we choose to maintain the 0.4 mm G1 aperture diameter. For the higher resolution requirement, the depth of the common lens and the object distance were increased. The former will enlarge equivalence main lens diameter and spherical aberration was reduced. The latter will cause larger object distance, i.e., smaller magnification. According to the modeling results, the spotsize of the new gun is 25.8% better in horizontal direction and 8.6% in vertical direction than our conventional "CLEAR" gun. |
