| Outline of Final Research Achievements |
In this challenging exploratory research, we adopted a localized field detection method using a 200 keV scanning transmission electron microscope with a strong liquid permeability, developed the SiN membrane electrolytic cell, and we created the localized field detection technique by the offset type HARDF detection method. An offset of about 1.3 mm was given to the electron beam axis with respect to the center of the HARDF detector having an inner diameter of 3 mm. The projection lens system was adjusted to have the camera length of 2.23 m. With respect to electrons transmitted through the electrolytic cell, the transmitted electron beam gives 50% HARDF detection intensity at a deflection angle of 0.3 mRad and it is possible to image scattered electron information scattered in the localized field formed in the liquid.
