Pulse shape discrimination (PSD) is one of the most distinctive features ofliquid scintillators. Since the introduction of the scintillation techniques inthe field of particle detection, many studies have been carried out tocharacterize intrinsic properties of the most common liquid scintillatormixtures in this respect. Several application methods and algorithms able toachieve optimum discrimination performances have been developed. However, thevast majority of these studies have been performed on samples of smalldimensions. The Counting Test Facility, prototype of the solar neutrinoexperiment Borexino, as a 4 ton spherical scintillation detector immersed in1000 tons of shielding water, represents a unique opportunity to extend thesmall-sample PSD studies to a large-volume setup. Specifically, in this work weconsider two different liquid scintillation mixtures employed in CTF,illustrating for both the PSD characterization results obtained either with theprocessing of the scintillation waveform through the optimum Gatti's method, orvia a more conventional approach based on the charge content of thescintillation tail. The outcomes of this study, while interesting per se, arealso of paramount importance in view of the expected Borexino detectorperformances, where PSD will be an essential tool in the framework of thebackground rejection strategy needed to achieve the required sensitivity to thesolar neutrino signals.
