“…Like X ray radiography, the suitable radioactive source should be provided for neutron radiography. To obtain fast radiographic images and good position resolution of neutron radiography, the necessary neutron source used today should be provided by nuclear reactor or spallation neutron sources followed by a neutron collimator [2][3][4]. Furthermore ideal neutron beams for neutron radiography should be parallel, monoenergetic, high flux possessing no other radiation with good uniformity at its cross section.…”

For the research of CCD neutron radiography, a neutron collimator was designed based on the exit of thermal neutron of the Boron Neutron Capture Therapy (BNCT) reactor. Based on the Geant4 simulations, the preliminary choice of the size of the collimator was determined. The materials were selected according to the literature data. Then, a collimator was constructed and tested on site. The results of experiment and simulation show that the thermal neutron flux at the end of the neutron collimator is greater than 1.0 × 10 6 n/cm 2 /s, the maximum collimation ratio (L/D) is 58, the Cd-ratio(Mn) is 160 and the diameter of collimator end is 10 cm. This neutron collimator is considered to be applicable for neutron radiography.
