TOMCAT2.0 Progressing Toward Initial User Operation.
The TOMCAT2.0 Upgrade project is steadily advancing, with the S-TOMCAT beamline now being gradually brought online. On June 25th, 2025, it successfully received first light from the SLS2.0 2.1 T bending magnet. We anticipate hosting initial pilot experiments by the end of the year. During the early 2026 shutdown, we plan to install the 5 T superconducting bending magnet, aiming to achieve full operational specifications by Q2 2026.
Preparations are also underway to bring I-TOMCAT to first light in Q3 2025. This new insertion-device beamline will feature three state-of-the-art endstations, dedicated to high-resolution, high-throughput, and dynamic tomographic imaging.
Both S-TOMCAT and I-TOMCAT are on track to begin regular user operations in July 2026.

Jisoo Kim bags the 2022 Werner Meyer-Ilse Award
Jisoo Kim was awarded the 2022 Werner Meyer-Ilse Memorial Award. The WMI Award is given to young scientists for exceptional contributions to the advancement of X-ray microscopy through either outstanding technical developments or applications, as evidenced by their presentation at the International Conference on X-ray Microscopy and supporting publications. Jisoo was awarded for his development of the method "Time-resolved x-ray scattering tomography for rheological studies", and is co-recipient of the award with Yanqi Luo from the Advanced Photons Source for her work on applications. The award was presented during the 15th International Conference on X-ray Microscopy XRM2022 hosted by the National Synchrotron Radiation Research Center (NSRRC) in Hsinchu, Taiwan on 19 - 24 June, 2022.
TOMCAT welcomes on board two scientists
The X-ray Tomography group welcomes on board Mariana Verezhak and Goran Lovric as members of the TOMCAT beamline crew. They will both contribute to the further development and realization of TOMCAT 2.0 (S- and I-TOMCAT branches on SLS2.0).
