Detector for Advanced Neutron Capture Experiments (DANCE)

DANCE is a 4π detector array that consists of up to 160 elements of barium fluoride crystals. It is designed to study capture reactions on small quantities of radioactive isotopes (down to 1 mg or up to 1 Ci), which are of interest to studies in nuclear astrophysics and stockpile stewardship science.

DANCE is located on the 20 m neutron flight path 14 (1FP14) at the the Manuel Lujan Jr. Neutron Scattering Center at the Los Alamos Neutron Science Center (LANSCE) at the Los Alamos National Laboratory. The neutrons are produced via spallation reactions caused by an 800 MeV proton beam hitting a tungsten target with typical beam currents of 100 uA. Depending on the flight path, the fast neutrons are moderated by water or other moderators.
