- Abstract
The Pneumatic Fast Transfer System irradiation channel of KAMINI reactor was characterized using Høgdahl and Westcott formalism. The neutron spectrum parameters like epi-thermal flux shape factor (α), thermal to epi-thermal neutron flux ratio (f), Modified Spectral Index ( r 0 T n / T 0 ) and Westcott factor gLu(Tn) were determined by measuring the activity corresponding to the (n,γ) product of nuclides having cross-section behavior "l/v" (197Au, 94Zr, and 58Fe) and "non-l/v" (176Lu). The obtained gLu(Tn) value was used to determine the neutron temperature (Tn) and further validated by fitting the thermal neutron spectrum, computed using MCNP. The Westcott parameters were validated by analyzing the reference materials.
