Abstract

Plastic scintillators available on the market suffer from radiation damage at doses much lower than the ones expected at the SSC. The two major effects are induced transmission losses and damage to the scintillating fluors. The dominant radiation-induced absorption effects in the blue part of the transmission spectrum can be remedied by the use of large Stokes shift fluors emitting in the green region above 500 nm. With these fluors, the newly produced scintillators based on polyvinyltoluene and polystyrene have greatly enhanced radiation resistance. In cases when even the improved plastic scintillators will fail, liquid scintillators can be used. When damaged, the active material can be replaced without dismounting detector modules. Contrary to expectations, our tests showed that standard liquid formulations are damaged at rather low radiation doses of 1–5 Mrad. Newly developed formulations are significantly more radiation resistant.
