Domestic FEU-130 photomultiplier tube with also domestic amplifier-discriminator are compared with a HAMAMATSU R7207-01 photomultiplier and С3866 amplifier-discriminator as applied to the problem of ozone sensing at the Siberian Lidar Station. It is shown that use of a R7207-01 photomultiplier provides for wider capabilities in extending the altitude range, in which ozone profiles can be reconstructed, upward and downward by 30% due to higher count rate and higher quantum efficiency as compared with those of the FEU-130 photomultiplier. In addition, application of a HAMAMATSU R7207-01 photomultiplier and С3866 amplifier-discriminator extends the altitude range of ozone profile reconstruction and improves the measurement accuracy by 10-15%.
