Abstract
Light attenuation, n-gamma pulse shape discrimination and timing prope rties of a long liquid scintillation detector (LLSD) were examined by means of Monte Carlo simulations and experiments. LLSD is a long recta ngular shaped NE213 scintillator (80 x 6.5 x 10 cm(3)) coupled with tw o photomultipliers and has been developed for neutron scattering exper iments. We found that an air gap between a photomultiplier and a scint illator cell worked as a filter and reduced position dependencies of p ulse height and of n-gamma pulse shape discrimination which were disad vantages on the use of LLSD, whereas it deteriorated n-gamma separatio n. This paper discusses the advantages and disadvantages of the air ga p to the detector properties.
