Northwestern University Center for Atom-Probe Tomography
Welcome to NUCAPT
As of Aug 27, 2020, NUCAPT is in Phase 3 "Summer Stabilization" (phase 3 of Northwestern's recovery plan). All users must follow the guidelines in NUCAPT's pandemic response plan. If you are a registered facility user, you should have received an e-mail with the requisite information. For remote APT data analysis, we will continue our program for remote access to the IVAS computer workstations. For details please consult with NUCAPT facility management. Please also see Northwestern's central core facilities status page and university guidelines for details of the phased return to campus.
NUCAPT is a research facility at Northwestern University directed by Founding Director Prof. David N. Seidman and Associate Director Prof. Derk Joester, and managed by Research Prof. Dieter Isheim. NUCAPT specializes in high-resolution chemical imaging by three-dimensional atom-probe tomography (APT). APT produces a three-dimensional (3D) atom-by-atom elementally and isotopically resolved image with sub-nanometer spatial resolution of a sample volume typically 100 x 100 x 300 nm3, by simultaneous high resolution direct-space imaging and atom-by-atom time of flight mass spectrometry. APT is particularly suited to study nano- or nanostructured materials. For more information about our facility please see this short video here (4:31 min). If you have questions about atom probe tomography or are interested in having your specimens analyzed at our facility, please give us a call or send an e-mail with your questions for more information; see the contact info in the profile of our facility manager.

Acknowledgements We depend on your acknowledging instrument usage at our NUCAPT facility and any staff support, by always including an appropriate acknowledgement statement in all publications, presentations, and releases containing data collected at NUCAPT. The default acknowledgement statement is as follows: Acknowledgements: Atom-probe tomography was performed at the Northwestern University Center for Atom-Probe Tomography (NUCAPT). The LEAP tomograph at NUCAPT was purchased and upgraded with grants from the NSF-MRI (DMR-0420532) and ONR-DURIP (N00014-0400798, N00014-0610539, N00014-0910781, N00014-1712870) programs. NUCAPT received support from the MRSEC program (NSF DMR-1720139) at the Materials Research Center, the SHyNE Resource (NSF ECCS-2025633), and the Initiative for Sustainability and Energy (ISEN) at Northwestern University. Also important: please send us your publications and citations that include work done at NUCAPT so that we can keep out literature database up to date! | |
Atom Probe Tomography WORKSHOP At NUCAPT's APT workshop Oct 22/23, 2019, offering training in the IVAS® APT data visualization and evaluation software, presentations of APT to a variety of materials analyses, and new techniques for correlative investigations that include APT, attendees were also invited to visit the NUCAPT laboratory and see one of the worldwide first installations of the CAMECA® AP Suite 6 in action.
