DESCANT and β-delayed neutron measurements at TRIUMF

The DESCANT array ( D euterated S cintillator A rray for N eutron T agging) consists of up to 70 detectors, each filled with approximately 2 liters of deuterated benzene. This scintillator material o_ers pulse-shape discrimination (PSD) capabilities to distinguish between neutrons and γ -rays interacting with the scintillator material. In addition, the anisotropic nature of n – d scattering allows for the determination of the neutron energy spectrum directly from the pulse height spectrum, complementing the traditional time-of-flight (ToF) information. DESCANT can be coupled either to the TIGRESS ( T RIUMF- I SAC G amma- R ay E scape S uppressed S pectrometer) γ -ray spectrometer [1] located in the ISAC-II [2] hall of TRIUMF for in-beam experiments, or to the GRIFFIN ( G amma- R ay I nfrastructure F or F undamental I nvestigations of N uclei) γ -ray spectrometer [3] located in the ISAC-I hall of TRIUMF for decay spectroscopy experiments.
