Title: Yutaka Yoribayashi: Innovator in Neutron Detection Technology

Introduction

Yutaka Yoribayashi is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of neutron detection technology, holding two patents that showcase his innovative approach to this complex area of research.

Latest Patents

Yoribayashi's latest patents include a neutron detector and a neutron image detector with scintillator. The neutron detector is designed without gas and features a translucent type plate neutron scintillator capable of emitting fluorescence from both sides. This scintillator is composed of a ZnS fluorescent substance and a neutron converter containing lithium or boron, arranged at a 45-degree angle to the incident neutrons. The design is housed within a cylindrical detector with a circular or square section, incorporating a specular reflector with a reflectance of 90% or more. The fluorescence emitted when neutrons enter the scintillator is detected by two photo multipliers positioned on either side, with the signals processed to produce a neutron signal.

The neutron image detecting method and its corresponding detector utilize a method that collects fluorescent light generated by neutron incidents at designated position intervals in a one-dimensional geometry. This method determines the incident position of neutrons by detecting the collected fluorescent light through a photon counting method. A pulse signal generated by an individual output photon is extracted based on a clock signal that matches the time width of the pulse signal. The count-value distribution is obtained in terms of incident position, allowing for the calculation of a median point based on the distribution.
