Development of fast neutron pinhole camera using nuclear emulsion for neutron emission profile measurement in KSTAR

We have developed a compact fastneutroncamera based on a stack ofnuclear emulsion plates and a pinholecollimator. Thecamera was installed at J-port of Korea superconducting tokamak advanced research at National Fusion Research Institute, Republic of Korea. Fastneutronimages agreed better with calculated ones based onMonte Carloneutron simulation using the uniform distribution of Deuterium-Deuterium (DD)neutron source in a torus of 40 cm radius.
