Light guides on the base of dielectric gel compositions

摘要

Light guides those have to shift the light of scintillator in a longer-wavelength region and collect this light on a photodetector are developed on the base of radiation resistant gel composition Sylgard-527. The luminescent molecules of POPOP(1, 4-bis-(2 (5-phenyloxazole))-benzene), PB (1, 4-diphenyl-1, 3-butadiene), or TP (p-terphenyl) were introduced in the composition. We study the total number of accounts S in the range of the spectrum, it relative value SR, the light transmittance T before and after irradiation. The best results were obtained with POPOP and TP.
