Crystal Press Forging for Large Scintillator Development

Crystal Press Forging for Large Scintillator Development 

The typical view of pressed scintillation crystal is shown in Fig. 14.13. From initial single crystals, 400-500 mm in diameter, sizes of polycrystalline slab of 800-1000 mm, and more, are easily obtainable. 

The above example points out the importance of complementary production technologies for large-size crystals. This kind of technology does not require development of dedicated sophisticated equipment, and it is not capital intensive, which is different from the hardware used in continuous single-crystal growth. However, when combined, they allow, for example, for rapid R D and fabrication of detectors for SPECT systems.
