Cluster researchers, including Doctoral Researchers Jannis Weinacker and Sebastian Kalt, Principal Investigator Martin Wegener, and Alumnus Maximilian Bojanowski, have developed the first two-photon 3D-printable plastic scintillator. This innovation enables micrometer precision and optical-grade surfaces, as demonstrated in the KATRIN experiment. While the light yield is below that of commercial scintillators, it provides the basis for advanced high-resolution detectors in particle physics and medical imaging.
