Cooperative development of novel scintillators for ultrafast radiation detectors (SCINT-UFRD)

Currently, the scintillator is the bottleneck for the construction of an ultrafast detector for use in medical imaging and high-energy physics. Therefore, developing novel scintillators with superior timing characteristics is an urgent task. Promising candidates are materials exhibiting an intenseultrafast cross-luminescence (CL). We plan to develop such a CL scintillator suitable for fast-timing applications by carefully designing a novel fluoride CL scintillator. The collaboration between both groups will result in synergistic research. The Japanese team offers a well-equipped crystal growth laboratory and years of experience with crystal growth of fluoride materials. The micro-pullingdown technique enables high throughput material screening while the Czochralski technique allows growing high-quality, large-volume crystals. The Czech team offers state-of-the-art characterization equipment and experts on the materials design and evaluation of scintillator performance. Collaboration between these two teams thus can significantly progress the development of ultrafast scintillators.
