説明
A novel multipoint radiation monitor using waveguide scintillators and optical fiber connections is described. A new design of waveguide scintillator consisting of a scintillating material and a wavelength-shifting fiber (WLSF) has been deeveloped. The WLSF is embedded in the scintillator, and each end is fitted with an optical connector for connection to a transparent optical fiber. Multiple waveguide scintillators can be connected in a series, and the ends of the transparent optical fiber loop are terminated with a pair of photodetectors. This new technique for radiation monitoring dispenses with electric apparatus and improves noise resistance. Furthermore, it offers the advantages of multipoint measurement, meaning that the radiation incident on each scintillator is monitred by two photodetectors. We have examined the light output characteristics and time resolution of a prototype arrangement of waveguide scintillators and confirmed the feasibility of multipoint measurements in a system of five waveguide scintillators connected in series using a 200 m optical fiber loop.
