Characterization of multiplicity filter module

The National Array of Neutron Detectors (NAND) facility at IUAC is a multi-detector array for the study of nuclear reaction around the Coulomb barrier. The array is being used for prescission neutron multiplicity measurements to study fission time scale, quasi-fission characteristics, etc. where signals from any of the fission detectors in coincidence with rf of the beam pulse was used as the acquisition trigger. All the neutrons interacted with neutron cell within a given time window (400 ns or 500 ns) were included in the acquisition
