  • Patent number: 7679064
    Abstract: The characteristics of the phosphor ZnS:Ag,Cl which has a considerably high fluorescence yield in response to incident particles thus allowing for their easy detection are used as such and combined with the finding that the fluorescence components in the range of shorter wavelengths are short-lived, which led to an improvement of counting characteristics, hence allowing for high-rate measurements of particles. When B370 was used as an optical filter to pick up fluorescence components shorter than 450 nm, the decay time of short-lived fluorescence components could be reduced from 370 ns to 200 ns.

  • Patent number: 7326933
    Abstract: A radiation or neutron detector wherein lateral side light detecting optical fibers prepared from clear optical fibers that are scraped on a lateral side to permit side incidence of fluorescence are used to detect the fluorescence from a phosphor or a scintillator such that the background to gamma-rays is reduced. If desired, the optical fibers may be bent at 90 degrees and guided to a photomultiplier tube in order to reduce the size of the detector. Fabrication and maintenance of the detector can be facilitated by adopting such a design that a detecting block comprising a detection medium and lateral side light detecting optical fibers is separated from a readout block comprising clear optical fibers.
