The TEAM Project
Pioneering developments of aberration-correcting electron optics have created the unprecedented opportunity to directly observe the atomic-scale order, electronic structure, and dynamics of individual nanoscale structures by advanced transmission electron microscopy. It is foreseeable that aberration corrected electron microscopes exhibiting deep sub-Ångstrom resolution with single atom sensitivity and an increased time - and energy resolution can be constructed within the next few years. The substantial expense of developing and maintaining such aberration-corrected electron microscopes is beyond the ability of individual investigators or even university centers. To address this need, the Department of Energy’s electron beam microcharacterization centers proposed the development of a new generation of advanced electron microscopes built around aberration-correcting optics. The TEAM project (Transmission Electron Aberration-corrected Microscope) was initiated as a collaborative proposal involving five DOE-supported electron beam microscopy efforts, located at Argonne National Laboratory, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, Oak Ridge National Laboratory, and Frederick Seitz Materials Research Laboratory. The vision for the TEAM project is the idea of providing a sample space for electron scattering experiments in a tunable electron optical environment by removing some of the constraints that have limited electron microscopy until now. The resulting improvements in resolution, the increased space around the sample, and the possibility of exotic electron-optical settings will enable new types of experiments.
The project was presented to the Office of Basic Energy Sciences in October 2002. As a DOE Project, TEAM is subject to specific rules that control its progress via a series of critical decisions CD0-CD4. CD0 (Mission Need) was granted in May 2004, CD1 (Alternative Selection and Cost Range) was signed in September 2005 after a critical design review in April 2005. The Conceptual Design review was signed in April 2006, and the CD2/3 review (Approval of Project Baseline/Readiness to Execute) was signed in December 2006.
TEAM is guided by a scientific advisory committee. The project is a collaboration of several DOE-funded efforts and two commercial partners (FEI and CEOS). Led by the National Center for Electron Microscopy, the project pursues several key developments in parallel, with each partner responsible for a specific set of tasks (ORNL – STEM corrector, UIUC – beta stage, ANL – Cc corrector, CEOS – correctors, FEI – column). The TEAM project is part of DOE’s 20-year roadmap of Facilities for the Future of Science, and after its completion in 2009, the instrument will be made available to the scientific user community at the National Center for Electron Microscopy. The machine is being implemented in two stages – TEAM 0.5 will become available as a user facility in October 2008 and TEAM I in October 2009.
TEAM OutreachInput from the scientific community in the form of workshops, discussions and presentations has been important in shaping the project since its inception.
Periodic updates on the status of TEAM were presented at the annual meeting of the Microscopy Society of America in Honolulu in August 2005 TEAM Update 2005.pdf, at the Spanish Microscopy Society in Bilbao, July 2007 TEAM SME 2007.pdf, at the Microscopy Society of America in Fort Lauderdale, August 2007 TEAM status 2007.pdf, at the American Vacuum Society in Seattle, October 2007, at the Portuguese Microscopy Society in Coimbra, December 2007 TEAM Incomam.pdf, and at the European Microscopy Society in Aachen, July 2008 TEAM EMC 2008.pdf and at a number of university department colloquia (MIT, Stanford, Northwestern, Harvard)
A workshop was held at NCEM on June 23, 2008 to explore the possibilities for remote operation of the TEAM instrument after it starts operations. The goal of this meeting was a plan to "extend the TEAM control room" to the partner labs and to enable “access portals” at participating National Laboratories, linked to TEAM through a high performance network line such as that provided by ESnet.
