Description
A new cold neutron prompt gamma activation analysis (CN-PGAA) system has been developed at the HANARO cold neutron source. The CN-PGAA is installed at the end position of a CG2B neutron guide. It was designed to be composed of an n-type HPGe and a BGO and will be operated in single bare, Compton suppression and pair spectrometer modes, and there is a gap for a beam chopper for a time-of-flight PGAA. The sample box is made from Teflon for He-filled or vacuum environments. The neutron beam profile and neutron flux are simulated using a McSTAS code and measured by time of flight and gold activation methods. Neutron temperature at sample position is about 40K and the true integrated neutron flux to be over 5.0x108 n/cm2s. Its performance has been tested by using various certified reference materials
