Latest Patents

Fujita's latest patents focus on innovative designs for plastic scintillating fibers. One of his notable inventions includes a plastic scintillating fiber that incorporates an organic compound with a neutron cross section larger than that of hydrogen. This fiber features an outermost peripheral layer made of a plastic material that emits scintillation light when exposed to neutron radiation. Inside this layer, a core with a high refractive index contains fluorescent substances that absorb and wavelength-convert the scintillation light. Additionally, a cladding layer surrounds the core, having a lower refractive index, which enhances the fiber's performance.

Another significant patent describes a plastic scintillating fiber that includes an outermost layer made from a heavy metal compound and a resin with scintillating properties. The core, situated within this layer, also contains fluorescent substances that absorb light generated from the outer layer and convert it into longer wavelengths. This design further integrates the core, cladding layer, and outermost layer into a cohesive structure, improving the efficiency of the fiber.
