Abstract
The article presents a study on the hole count and secondary excitation in analytical electron microscope. Hole count spectra was measured in several AEMs and compared to those produced by direct excitation of molybdenum support by the high energy electrons at reduced beam current. It was observed that electrons are the primary source of hole count in this case. It was supported by the presence of a small chromium Kα peak in the hole count spectrum. High energy x-rays interaction with thick chromium film should produce negligible chromium x rays. These results were also obtained from other AEMs.
