Title:
プラスチックシンチレーションファイバ及びその製造方法
Document Type and Number:
Japanese Patent JP6963547
Kind Code:
B2
Abstract:
Provided is a plastic scintillating fiber capable of reducing modal dispersion and improving the accuracy of identifying a position which radiation passes through. A plastic scintillating fiber according to one aspect of the invention includes a core (1) and a cladding (2) that covers an outer periphery of the core (1) and has a lower refractive index than the core (1). The core (1) uniformly contains a radiation-emitting fluorescent agent (3) and has a refractive index distribution where the refractive index of the core (1) is highest at a center of a cross-section and becomes lower in a parabolic manner with distance from the center toward an outer periphery.
