Abstract

In the present study, the multi-detectors device was designed for landmine detection based on the MCNP simulation. With the D-T neutron generator and BGO detectors set as the core of device, boron-doping polyethylene with 5% boron was chosen for decreasing the activated noise in device. Based on the designed device, the method was proposed to detect the accurate position of buried landmine by discussing the relationship of nitrogen response between different detectors. With the calculation of simulation results, it indicated the accurate position of landmine could be acquired with a small deviation according the method. Finally, based on the established device, experimental measurement was made for furtherly investigating the validity of method.
