Thermal neutron die-away times in large samples irradiated with a pulsed 14 MeV neutron source

  • Frank Mildenberger
  • Eric Mauerhofer


In order to measure delayed gamma-rays without appreciable interferences of prompt gamma-rays, thermal neutron-die-away times in different large samples irradiated with 14 MeV pulsed neutrons at the MEDINA facility are studied. The die-away times are found to range between 2 and 5 ms according to the irradiated materials. For the acquisition of the delayed gamma-rays spectra a waiting time of about 12 ms after the end of the neutron pulses is needed.
