摘要：

As an application of the wavelength-shifting (WLS) fiber technique recently developed in the field of high-energy physics, a novel type of imaging device for neutrons has been successfully investigated; a space resolution of I mm FWHM with detection efficiency of 55% for 10 Angstrom neutrons has been experimentally confirmed with a prototype made of a 0.5-mm-thick ZnS(Ag) + (LiF)-Li-6 scintillator plate optically coupled to WLS fiber arrays. In addition to promising results obtained in this study, its simple structure and reliable operation allow us to foresee a new generation of imaging devices to meet the increasing demand for large-area and high space-resolution imaging devices for several new projects on spallation neutron sources in the world.
