    abstract = "The polystyrene-based scintillator UPS 923A was chosen for upgrading of
the muon system for the CDF detector at the Fermilab Tevatron.
Properties of this scintillator such as light output, light attenuation,
long-term stability and also timing characteristics of scintillators and
wavelength-shifting fibers were investigated. The method for the Bulk
Attenuation Length measurements of the scintillator to its own light
emitted was proposed.
Comparison measurements of the characteristics of the UPS 923A and the
polyvinyltoluene-based scintillator NE 114 are done. It was found that
natural aging of the NE 114 was two times faster than that of the UPS
923A. (c) 2005 Elsevier B.V. All rights reserved."
