LiCAF single crystals are excellent materials for neutron/gamma discrimination because of their low gamma-ray sensitivity due to their low density of 2.99 g/cm³ . The Eu-doped LiCAF has a large luminescence and the Ce doped LiCAF has a short decay time.
We commercialize crystals, arrays, and fibers for BNCT. The raw Li is available in natural and ⁶Li 95% enriched, and the neutron sensitivity can be adjusted. LiCAF flexible sheet is a transparent sheet with 0.9 to 3.6x10²¹ atom/cm³ fine LiCAF crystals dispersed in silicone resin. It is possible to make a large area of this.
It can be used as an alternative to ³He, neutron imaging, neutron diffraction, and survey meter.
