Abstract
The design and construction of an array for delayed-neutron decay spectrosc opy is presented. The array is composed of 32 plastic scintillator (BC400) modules each of which provide for time-of-flight (energy) and position meas urements. The intrinsic detection efficiency is 30% at E-n = 2 MeV and the resolution deltaE(n)/E-n similar to 10% (FWHM). The array can cover a total solid angle of up to 50% of 4 pi. Details of studies performed to optimize the performances of the individual modules are reported, as well as source testing and in-beam commissioning. (C) 2000 Elsevier Science B.V.
