Ultrahigh resolution radiation imaging system using an optical fiber structure scintillator plate

Abstract High resolution imaging of radiation is required for such radioisotope distribution measurements as alpha particle detection in nuclear facilities or high energy physics experiments. For this purpose, we developed an ultrahigh resolution radiation imaging system using an optical fiber struc...
