<p>The Energy-Resolved Neutron Imaging System RADEN, located at the J-PARC Materials and Life Science Experimental Facility, is the world's first dedicated high-intensity, short-pulsed neutron imaging beam line. To carry out energy-resolved neutron imaging at RADEN, we use cutting-edge detector systems, recently developed in Japan, employing micro-pattern detectors or fast Li-glass scintillators coupled with high-speed, all-digital data acquisition systems. These counting-type detectors provide sub-μs time resolution, high neutron count rates, and event-by-event gamma rejection. The detectors available at RADEN offer a range of spatial resolutions from 0.25 to 3 mm and counting rates up to 8 Mcps. In the present paper, we show the performance of these detector systems as measured at RADEN and discuss ongoing development efforts aimed at improving spatial resolution and count rate performance.</p>
