Duffield Hall 150

The Thermo Fisher Spectra 300 STEM (Andromeda) is a high resolution aberration corrected scanning transmission electron microscope that will enable the study of magnetic materials at atomic resolutions at the CCMR. Andromeda has a unique lens design that magnetically decouples the minicondenser from the objective allowing for field free, aberration corrected imaging of magnetic domains with spatial resolutions of ~3Å. In addition, Andromeda is equipped with an EMPAD G-2 detector, an X-CFEG ultra-high brightness source, and Dual-X EDX detector with 1.8 srad solid angle.
