Abstract :
The design and construction of an array for delayed-neutron decay spectroscopy is presented. The array is composed of 32 plastic scintillator (BC400) modules each of which provide for time-of-flight (energy) and position measurements. The intrinsic detection efficiency is 30% at En=2 MeV and the resolution δEn/En∼10% (FWHM). The array can cover a total solid angle of up to 50% of 4π. Details of studies performed to optimize the performances of the individual modules are reported, as well as source testing and in-beam commissioning.
