Neutron Counting Type Imaging Detector With Super-Resolution Technique

A combination of a neutron image intensifier and a photomultiplier tube array was developed as a neutron imaging device for time-of-flight measurement. The device had an advantage in the neutron counting measurement because of the proportionality to the neutron intensity. A problem was in poor spatial resolution by the photomultiplier tube array, so the super resolution ability based on the center-of-mass calculation was attached to the newly developed data taking system. We confirmed its ability of time-of-flight measurement through the trial experiment. The super-resolution system also operated without failure.
