Current results are described on the research and development of the advanced humanitarian landmine detection system by using a compact discharge-type fusion neutron source called IECF (Inertial-Electrostatic Confinement fusion) devices. With a 50 mm-thick water-jacketed IEC device (IEC20C) of 200 mm inner diameter can have produced 10⁷ neutrons/s stably in CW mode for 80 kV and 80 mA. Ample 10.8 MeV -rays produced through (n,) reaction with nitrogen atoms in the melamine (C₃H₆N₆) powder (explosive simulant) are clearly measured by a BGO-NaI-combined scintillation sensor with distinct difference in case of with/without melamine, indicating identification of the buried landmines feasible.
