Development of Neutron Imaging Detector Using Capillary Phenomena and Liquid Scintillator

We have been developing a new type of neutron imaging detector with position resolution better than 10 micrometer by absorbing liquid scintillator for neutron capture into a capillary plate by capillary phenomena. Establishing the methods to absorb liquid scintillator to the capillary plate and attaching it into a photomultiplier, we irradiated the detector with neutrons and alpha particles. From the results of basic experiments, it was recognized that the capillary plate absorbing liquid scintillator can operate as a neutron detector
