Abstract

Abstract New types of polystyrene-based scintillators were tested regarding long-term stability, radiation resistivity and the saturation of light emission for large dE dx . They were compared with SCSN38m, which has often been used in high-energy physics experiments. Tests carried out over four years have shown that the changein the observed light yield is less than 10% in 1000 days for most of the tested scintillators. The SCSN81T2 type was found to be strong against radiation damage. There was no significant difference among the tested scintillators regarding the saturation of light emission for a large dE dx . For three new types (SCSN61T2, SCSN81T2 and SCSN81T2B) it was found that their observed light yield is greater than that of SCSB38. The light attenuation length of these types is also much longer than that of SCSN38.
