Abstract
A distribution type detector comprises scintillation fibers identical in length to each other, an optical delay fiber having a refractive index substantially identical to those of cores and claddings of the scintillation fibers, photosensitive elements, preamplifiers, constant fraction discriminators, a time-to-pulse height converter, an analog-to-digital converter, and a multichannel pulse-height analyzer. A position where a radiation falls on its corresponding scintillation fiber, is detected based on a difference between time intervals necessary for propagation of optical pulses produced in the corresponding scintillation fiber by the radiation. Thus, even if the length of each scintillation fiber is increased, position resolution can be kept high and a measuring circuit system can be simplified.
