To carry out energy-resolved neutron imaging at RADEN, we use cutting-edge detector systems employing micro pattern detectors and data acquisition systems based on Field Programmable Gate Arrays to provide the necessary sub-$$mu$$s time resolution, high counting rates, and event-by-event background rejection. One such detector, the Micro Pixel Chamber-based Neutron Imaging Detector ($$mu$$ NID), provides a spatial resolution of 120 $$mu$$ m ($$sigma$$), time resolution of 0.6 $$mu$$s, 18% detection efficiency for thermal neutrons, and effective $$gamma$$ sensitivity of less than 10-12. We have recently increased the rate capacity from 600 kips to more than 4 MPs via an upgrade of the front-end electronics and tested a new gas mixture optimized for better spatial resolution and higher detection efficiency. In this presentation, we will discuss the ongoing development of the $$mu$$ NID and show results of recent on-beam tests performed at RADEN.
