Abstract
Luminescent and optical characteristics of liquid scintillators intend ed for use in tracking detectors and calorimeters are presented. Eight bases and about 60 new scintillation dyes were investigated. The scin tillation efficiency of the 1MN- and IPN-based liquid scintillators do ped with R6, R15, R39, and 3M-15 is by 34-52% higher than that of a st andard polystyrene scintillator. In the 0.5-mm-diameter quartz capilla ries, an attenuation length of 319 cm has been obtained for IPN + 3 g/ l 3M-15. The characteristic light decay times of the liquid scintillat ors are 6.2-7.6 ns. The scintillation efficiency of liquid scintillato rs based on 1MN and IPN is by 22-32% higher in vacuum than in air. Cap illaries filled with liquid scintillators are compared with plastic fi bers.
