The Division of Analytical Electron Microscopy, IMR is a division of the Analytical Research Core for Advanced Materials (ARCAM) at the Institute for Materials Research (IMR), Tohoku University, providing technical support for nano- and meso-scale microstructural observation, crystal structure analysis, and chemical composition analysis using transmission electron microscopy.

History
ARCAM (the Analytical Research Core for Advanced Materials) was formed through the merger of two predecessor lineages: one responsible for chemical analysis and the other for electron microscopy.
| 1954 | The Common Analysis Laboratory was established to develop and improve chemical analysis methods (one of ARCAM’s predecessor organizations, and the origin of today’s Elemental Analysis Room). |
| 1984 | The Division of Analytical Electron Microscopy was established, initially operated by technical staff only (the other predecessor organization of ARCAM). |
| 1998 | The Division of Analytical Electron Microscopy came under the Common Analysis Laboratory, and ARCAM (the “Analysis Core”) was formed. |
| 2015 | The ARCAM Internal Regulations were enacted, formally separating the Elemental Analysis Room and the Division of Analytical Electron Microscopy, IMR into official divisions. |
| 2022 | The ARCAM Internal Regulations were revised. In connection with participation in MEXT’s Advanced Research Infrastructure for Materials (ARIM) program (launched in FY2021), the ARIM Project Unit was newly established, reorganizing ARCAM into its current three-division structure. |
| Present | As a research platform for the Institute and the University, ARCAM supports materials research through contract elemental analysis of inorganic materials, technical support via transmission electron microscopy, and development of analytical techniques. As part of this work, ARCAM also participates in MEXT’s Advanced Research Infrastructure for Materials (ARIM) program, providing shared equipment access to researchers outside the University. |
Organizational Structure
ARCAM is a research support organization established under the Institute for Materials Research, Tohoku University ARCAM Internal Regulations, and consists of the following three divisions:
Elemental Analysis Room
Responsible for elemental analysis of materials using ICP optical emission spectrometry, ICP mass spectrometry, atomic absorption spectrometry, gas analysis (carbon, sulfur, oxygen, nitrogen, hydrogen), X-ray fluorescence analysis, and related methods.
Division of Analytical Electron Microscopy, IMR
Responsible for nano- and meso-scale microstructural observation, crystal structure analysis, and chemical composition analysis using transmission electron microscopy.
ARIM Project Unit
Serves as the implementing unit for MEXT’s Advanced Research Infrastructure for Materials (ARIM) program, providing shared equipment access to researchers both inside and outside the University.
ARCAM’s operations are overseen by the Core Chief (a professor of the Institute, serving a two-year term), and matters concerning organization and operations are deliberated by a steering committee chaired by the Core Chief. For details on eligibility, application procedures, and fees for each division, please see the usage guide pages.
