Detection properties of a neutron counter based on scintillator, wavelength shifter, and photomultiplier
A simple neutron counter based on a scintillator strip, a wavelength shifter rod, and a photomultiplier was constructed in order to compare the properties of such a detector to a commercially available /sup 3/He counter. A calculation of the number of photons per absorbed neutron showed that with the bright /sup 6/Li/sup 158/Gd(/sup 11/BO/sub 3/)/sub 3/ scintillator, light levels should he sufficient to perform pulse height discrimination. This has been experimentally demonstrated. Furthermore, the performance of this scintillation neutron counter has been measured in time-of-flight experiments where simultaneously, the neutron spectra were recorded with a /sup 3/He proportional counter.
