Techniques - aberration corrected TEM/STEM

The ASU Center for Aberration Corrected Electron Microscopy (ACEM) provides researchers with an unrivaled capability to understand the behavior of materials at the atomic level. Dedicated in February 2012, the center is considered one of the premier microscopy facilities in the United States and has become the design standard for aberration-corrected microscopy.

The center’s building was designed with exceptional physical stability in mind. To achieve the highest level of visual and spectral resolution in electron microscopy, it is necessary to minimize impacts of the environment in which the microscope operates. These impacts can include vibrations, noise, electrical fields, temperature changes, air currents, pressure pulses and even the presence of people.
