Aberration-Corrected Electron Microscopy (ACEM) Core

The new Spectra Ultra TEM microscope is ready for user training.  All potential users that plan to operate the new advanced TEM, please register in PPMS system (https://ppms.us/yale/login/?pf=42) to initiate the process.

To better maintain an active user community, we created a website at acem.yale.edu; That website is mainly for keeping the user community active with news, events, learning resources etc.

The Aberration Corrected Electron Microscopy Core, or ACEM, is a cutting-edge, university-wide shared user research facility that works in partnership with other core facilities at Yale. We serve the Yale community and also the larger community through collaboration efforts. Our core's focus is cutting-edge and high-throughput capability in TEM, SEM and FIB. 

We offer a variety of techniques, including X-ray spectroscopy (EDS), electron energy loss spectroscopy (EELS), transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), electron diffraction (ED), nano-beam electron diffraction (NBED), 4D-STEM, convergent beam diffraction (CBED), EELS, EDX, electron holography, in-situ biasing/heating/cooling, CL, holography, Lorentz mode for imaging magnetic materials, i-DPC, and tomography. 

We have space on Yale West Campus with one advanced TEM (Spectra Ultra X) and one advanced FIB dual-beam system.

Please find more information about West Campus here.
