Abstract
Neutron beam design was studied at the Syrian reactor (MNSR, 30Â kW) with a view to generating thermal neutron beam in the vertical irradiation sites for neutron radiography. The design of the neutron collimator was performed using MCNP4C and the ENDF/B-V cross-section library. Thermal, epithermal and fast neutron energy ranges were selected as <0.4Â eV, 0.4Â eV-10Â keV, >10Â keV, respectively. To produce a good neutron beam quality, bismuth was used as photon filter. In this design, the L/D ratio of this facility had the value of 125. The thermal neutron flux at the beam exit was about 2.548Â ÃÂ 105Â n/cm2Â s. If such neutron beam were built into the Syrian MNSR many scientific applications would be available using the neutron radiography.
