Description

The performance of transparent wavelength shifters (WLS) on the base of polymethylmethacrylate and organic luminophors has been studied. Measurements have been carried out in the near and far ultraviolet. Using multicomponent WLS covering the photomultiplier (PM) window, the maximum quantum efficiency of the PM photocathode was increased up to 30%. Due to the use of WLS in the gas Cherenkov counter (radiator Fr-12) a photoelectric efficiency 2.3 times higher than for FEU-110 has been obtained. Now the FEU-110 photoelectric efficiency equals to photoelectric efficiency of the 56DUVP PM. (orig.)
