Description

The measurement techniques developed at HI-13 Tandem Van de Graaff Accelerator Laboratory of CIAE employ a multi-segment fission chamber and two liquid scintillation neutron detectors. TOF (time of flight) techniques are used for primary neutrons to select the fission events induced by monoenergetic neutron from 2H(d, n) reactions instead of breakup neutrons from 2H (d, np) reactions. The fission neutron TOF spectra are measured in coincidence with the fission fragments to distinguish fission neutrons from other secondary neutrons. The method permits measurements to a fairly good accuracy under large neutron and gamma ray background
