On June 25th 2025, the S-TOMCAT beamline shutters were opened to receive first X-ray light from the new SLS 2.0 storage ring. On June 26th, full white X-ray beam generated with a 400 mA ring current was brought into the experimental hutch with all beamline shutters open. The beam path glowed purple due to the ionization of air by the X-ray beam (Slide 1). On June 27th, this milestone was marked by taking first X-ray tomographic images (Slide 2, 3). The TOMCAT beamline crew with PSI colleagues are all smiles for this milestone in the TOMCAT 2.0 upgrade project (Slide 4).
