Characterization and Resolution of VANDLE Modules*

The Versatile Array of Neutron Detectors at Low Energies (VANDLE) is being developed to study the properties of unstable nuclei via (d,n) reactions and beta-delayed neutron emission. It is composed of scintillator bars of two sizes, 60 cm and 2 m, coupled to photomultiplier tubes. Twenty of these bars have been constructed into VANDLE modules and voltages have been gain matched for various energy ranges, and attenuation lengths measured. Measurements were recorded for position and timing resolutions of each module. The results of these characterizations with respect to different assembly parameters will be presented.
