A new PGNAA facility has been installed at horizontal channel of the Dalat research reactor. The facility consists of the following parts: collimators, beam stopper, sample holder table, beam catcher, and biological shielding. The construction takes into account the basic parameters associated with the facility, such as adequate thermal neutron flux and cadmium ratio, good signal-to-background condition, small gamma-ray contamination in the beam and appropriately low dose-rate to the operating personnel. |
