In this paper, the possibility using micromegas (Micro-Mesh Gaseous Structure) as neutron detector in 14 MeV neutron computed tomography (CT) is studied by simulation. The simulation results show that micromegas neutron detector has high spatial resolution and is a good candidate for neutron radiography. The three-dimensional images of plant roots in soil are successfully and clearly obtained by the 14 MeV neutron CT with micromegas as neutron detector. In the present simulation, MCNP is employed for 14MeV neutron transport in the sample and Matlab for the 3-D photograph reconstruction.
Keywords:micromegas detector;neutron CT;image reconstruction;root visualization
