This paper reports on development of pulsed neutron imaging for phase differentiation between liquid water and ice with introduction of a gated image intensifier. Previous neutron-imaging systems for phase differentiation between liquid-water and ice, on the other hand, had some issues with temporal resolution, horizontal distribution of neutron wavelength, and field-of-view size. By using energy-selected pulsed neutron imaging with an optical image intensifier, the authors have achieved liquid-water/ice phase identification with a shorter temporal resolution than before with a suitable field of view area to observe commercial PEFCs.
