PULSE SHAPE DISCRIMINATION IN A PLASTIC SCINTILLATOR
Journal Article
·
· IRE Trans. Nuclear Sci.
A plastic scintillator was developed which shows a decay time dependent upon energy loss per unit distance, and, therefore, is suitable for use with pulse-shape discrimination methods. This scintillator was employed in conjunction with an improved discrimination system and the data were analyzed on a two-dimensional analyzer which provided a matrix of 72 x 64 channels. At a bias level where 99% of the electron scintillations were eliminated, it was possible to obtain almost 100% counting efficiency for recoil protons of 2 Mev, and the scintillator was useful for protons down to 0.5 Mev. The influence of various monomers, polymerization conditions, scintillating solutes, and secondary solvents was investigated, and a preliminary survey of the effects of these variables on pulse-shape discrimination is presented.
