Facility at CIRUS reactor for thermal neutron induced prompt γ-rayγ-ray spectroscopic studies

A facility for prompt γ-rayγ-ray spectroscopic studies using thermal neutrons from a radial beam line of Canada India Research Utility Services (CIRUS) reactor, Bhabha Atomic Research Centre (BARC), has been developed. To carry out on-line spectroscopy experiments, two clover germanium detectors were used for the measurement of prompt γγ rays. For the first time, the prompt γ–γγ–γ coincidence technique has been used to study the thermal neutron induced fission fragment spectroscopy (FFS) in 235U(nth, f). Using this facility, experiments have also been carried out for on-line γ-rayγ-ray spectroscopic studies in 113Cd(nth, γγ) reaction.
