Development of a pixel detector for ultra-cold neutrons

A pixel detector with high spatial resolution and temporal information for ultra-cold neutrons is developed based on a commercial CCD on which a neutron converter is attached. 10B and 6Li are tested for the neutron converter and 10B is found to be more suitable based on efficiency and spatial resolution. The pixel detector has an efficiency of 44.1±1.1%44.1±1.1% and a spatial resolution of 2.9±0.1μm (1 sigma).
