Breakthrough Achievement: Thinnest Pixel Detector Sets Unprecedented World Record

The Belle II cooperation project has achieved a major milestone by successfully installing the thinnest-ever pixel detector, the size of a soda can, at the SuperKEKB accelerator in Japan. Developed to detect signals from particle decays, the detector aims to shed light on the matter-antimatter asymmetry observed in the universe. The installation marks the end of a long journey for the detector, which traveled from Germany to Japan. The pixel detector's DEPFET sensor technology can also be used for other purposes such as X-ray satellite missions, the search for sterile neutrinos or dark matter, and medical imaging.
