Abstract:

The 4π multi-detector γ-ray calorimeter DANCE at the Los Alamos Neutron Science Center and its recent upgrade with an array of neutron detectors NEUANCE are described. DANCE has proven its ability to measure prompt fission γ rays with a large number of γ-ray multiplicities. The prompt fission γ rays may exceed a multiplicity of 25 and total energy of 20 MeV. NEUANCE adds the option of neutron measurement in addition to γ-ray measurement with DANCE and thus to study the fission γ-n correlations. In addition, a pair of silicon detectors measuring the kinetic energy of the fission fragments enables research on the γ-n-TKE correlations. Preliminary results of correlated data from ²⁵²Cf(sf) and ²³⁵U(n, f) measurements are presented.
